Description

Technical Field

[0001] This utility model relates to a small washer-dryer combo machine, belonging to the field of washing machines. Background Technology

[0002] Washing machines are common household appliances. They typically handle large loads and are quite bulky, making them unsuitable for carrying or moving. However, with improved living standards and increased demands for laundry sorting, more and more families and frequent travelers are keeping small washing machines as spares. For example, they might use a larger, conventional washing machine to wash larger items, while using a smaller machine to wash underwear, socks, or baby clothes, allowing for separate laundry. Alternatively, for hygiene reasons, they might bring their own small washing machine with them on business trips.

[0003] Chinese utility model patent CN220116864U discloses a small underwear washing machine, belonging to the field of small washing machine technology. It includes a main shell and a water supply mechanism, including a water storage tank disposed inside the main shell, which can store and provide water for cleaning clothes; and a cleaning mechanism, including a drive motor disposed at the bottom of the main shell and a cleaning wheel connected to the output shaft of the drive motor. This small washing machine can clean clothes, but it has a complex structure and high cost. The complex structure will affect the weight of the washing machine, causing problems with inconvenience in carrying and transporting.

[0004] Existing products also include small washing machines that do not require a water supply system, but these small washing machines typically dry clothes by spinning, and the clothes still need to be air-dried afterwards, which is inconvenient to use. They cannot dry clothes quickly during travel or business trips, resulting in poor performance. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a small washer-dryer combo machine, which aims to solve the problem that existing small washing machines cannot dry clothes quickly after washing.

[0006] A small washer-dryer combo includes a base, on which are mounted a control unit, a washing tub, a drying tub, a power supply, a washing component, and a drying component. The base has an air outlet that communicates with the drying tub, and the drying component blows hot air through the air outlet to dry the clothes.

[0007] This invention integrates washing and drying into a single structure. The drying component directly introduces hot air into the drying drum through an air outlet on the base, enabling direct drying after washing. Compared to existing small machines that rely solely on spin-drying followed by air drying, this device can complete the "wash-dry" process within the same unit, or perform both functions simultaneously, significantly shortening the drying time of clothes and improving efficiency and convenience for users traveling or on business trips.

[0008] Preferably, the drying component includes a fan disposed in the base and electrically connected to the control component and the power supply. The fan is connected to an electric heating element. After the fan blows air, it is heated by the electric heating element so that the hot air is delivered to the drying drum through the air outlet to dry the clothes.

[0009] This technical solution involves a fan drawing in and propelling room temperature air, which is then heated by electric heating elements to form a stable stream of hot air that is delivered into the drying drum. The hot air acts on the surface of the clothes via convection, preventing localized overheating and achieving a more even and faster drying effect. By housing the fan and electric heating elements inside the base, the electrical and control components can be compactly integrated, reducing external components and complex piping, thus contributing to miniaturization and portability.

[0010] Furthermore, the base is provided with an air outlet groove, the air outlet is located on the side wall of the air outlet groove, the bottom surface of the air outlet groove extends in an inclined manner to the lower edge of the air outlet, the bottom surface of the air outlet groove and the lower edge of the air outlet are provided with a water-blocking step, and a water outlet is provided in front of the water-blocking step.

[0011] This technical solution guides condensate or external splashes generated during the drying process along the bottom of the tank to the outlet, preventing water from directly flowing into the fan, electric heating elements, and control components inside the base, thus reducing the risk of electrical short circuits and corrosion. The inclined bottom surface and directional air outlet help control the outlet angle and speed of the hot air, reducing turbulence and ineffective loss of hot air at the outlet. Combined with optimized control of the fan and heating elements, this improves heat utilization efficiency and energy consumption performance.

[0012] Furthermore, the base is provided with a water outlet that connects to the water outlet, which is used to drain the water dripping from the clothes inside the drying drum.

[0013] This technical solution allows for direct drainage of water dripping from clothes inside the drying drum, preventing water from accumulating in the air duct or base and reducing the risk of corrosion and electrical malfunctions caused by water buildup inside the machine. The water outlet can be quickly connected to hoses, drain pipes, or collection containers, facilitating centralized drainage or closed-loop recycling in environments such as hotels, dormitories, or the outdoors, enhancing the equipment's adaptability and flexibility.

[0014] Preferably, the bottom of the drying drum is provided with a detachable first isolation net, and the inner wall of the drying drum is provided with a plurality of vertically protruding support ribs at intervals, and the support ribs are provided with a detachable second isolation net.

[0015] This technical solution allows the first and second isolation nets to form two layers of space for storing clothes, increasing the efficiency of clothes drying. The isolation nets are detachable, allowing users or after-sales personnel to easily remove them for cleaning or replacement, simplifying daily maintenance procedures and helping to maintain equipment hygiene and reduce the possibility of bacterial growth. The isolation nets prevent large water droplets and fibers from entering the lower air duct or base, reducing contamination and corrosion of critical electrical components such as the fan impeller and electric heating elements, thereby extending the life of critical components and reducing maintenance frequency.

[0016] Furthermore, the base is equipped with ultraviolet disinfection lamps that are electrically connected to the control components and the power supply, and the ultraviolet disinfection lamps are distributed on both sides of the bottom of the drying barrel.

[0017] This technology utilizes ultraviolet (UV) disinfection lamps to sterilize the surface of clothes and the walls of the drying drum, effectively inactivating bacteria, viruses, and mold spores. This improves the hygiene of both the clothes and the drying drum, making it particularly suitable for applications requiring high hygiene standards, such as underwear and infant clothing. The UV lamps, combined with hot air generated by a fan / electric heating element, enhance the microbial inactivation rate through a synergistic effect of heat and light, shortening the disinfection time and enabling the washer-dryer cycle to perform disinfection simultaneously with drying.

[0018] Preferably, the base is further provided with a drive motor that is electrically connected to the control components and the power supply. The drive motor is rotatably connected to a drive shaft, and a washing impeller located at the bottom of the washing tub is fixedly connected to the drive shaft. The washing impeller is driven by the drive motor to rotate forward and backward to wash clothes.

[0019] This technical solution integrates the drive motor within the base, directly driving the washing impeller via a drive shaft. The short power transmission path and simple structure facilitate miniaturization and weight control, making it easy to carry and install. The impeller efficiently generates circulating water, enhancing the contact between detergent and clothing surfaces, achieving good cleaning results with less water. Combined with controllable motor speed and timer control, energy consumption is reduced. In use, simply add water to the washing tub; no external piping is needed to increase installation complexity, making it even more convenient to carry.

[0020] Preferably, the bottom of the base is provided with a mounting groove for installing a power supply, the power supply is fixedly installed in the mounting groove, and a removable cover plate is installed on the mounting groove.

[0021] This technical solution fixes the power supply in the mounting slot at the bottom of the base and adds a removable cover plate, which can effectively protect the power supply from external impacts, splashes, dust and foreign objects, reduce the risk of short circuits, corrosion and failure, and improve the safety and reliability of the whole machine.

[0022] Furthermore, the bottom of the base is also provided with heat dissipation grooves.

[0023] This technical solution provides a larger heat dissipation area and natural convection channels for the bottom of the base, enabling it to more quickly remove heat generated by components such as the power supply, drive motor, fan, and heating elements from the machine body, thus reducing the internal temperature. More even heat dissipation from the base prevents heat accumulation at the bottom, which could lead to reduced efficiency of the fan / heating elements, ensuring stable operation of the heating and air supply systems at the set power, thereby maintaining drying performance.

[0024] Preferably, the control component includes a button located on the side of the base, the button being used to control the activation and deactivation of the functions of each component.

[0025] This technical solution enables convenient operation of "one-button washing and drying," "individual disinfection," or "energy-saving mode," reducing user setup complexity and optimizing energy management, achieving a good match between human-computer interaction and energy efficiency. Users can easily access the device while using and carrying it, and can complete the on / off and mode switching with one hand, improving interaction efficiency and ease of use.

[0026] The beneficial effects of this utility model are as follows: This utility model integrates washing and drying into a single structure. The drying component directly introduces hot air into the drying drum through the air outlet on the base, achieving direct drying after washing. Compared with existing small machines that rely solely on spin-drying followed by air drying, this device can complete the "wash-dry" process in the same unit or perform both functions simultaneously, significantly shortening the drying time of clothes and improving the efficiency and convenience for users traveling or on business trips.

[0032] like Figure 1-5 As shown, this is an embodiment of a small washer-dryer combo machine of the present invention, including a base 1. The base 1 is provided with a control component, a washing tub 25, a drying tub 26, a power supply 21, a washing component and a drying component. The base 1 is provided with an air outlet 12 that communicates with the drying tub 26. The drying component blows hot air through the air outlet 12 to dry the clothes.

[0033] This invention integrates washing and drying into a single structure. The drying component directly introduces hot air into the drying drum 26 through the air outlet 12 on the base 1, enabling direct drying after washing. Compared with existing small machines that rely solely on spin-drying followed by air drying, this device can complete the "wash-dry" process within the same unit, or perform both functions simultaneously, significantly shortening the drying time of clothes and improving the efficiency and convenience for users traveling or on business trips.

[0034] The drying component includes a fan 27 located inside the base 1 and electrically connected to the control component and the power supply 21. The fan 27 is connected to an electric heating element 28. After the fan 27 blows air, it is heated by the electric heating element 28, so that the hot air is delivered to the drying drum 26 through the air outlet 12 to dry the clothes.

[0035] This technical solution involves the fan 27 drawing in and propelling room temperature air, which is then heated by the electric heating element 28 to form stable hot air that is delivered into the drying drum 26. The hot air acts on the surface of the clothes through convection, preventing localized overheating and achieving a more uniform and faster drying effect. By housing the fan 27 and the electric heating element 28 inside the base 1, the electrical and control components can be compactly integrated, reducing external components and complex piping, thus contributing to the miniaturization and portability of the machine.

[0036] The base 1 is provided with an air outlet 11, and the air outlet 12 is provided on the side wall of the air outlet 11. The bottom surface of the air outlet 11 extends in an inclined manner to the lower edge of the air outlet 12. The bottom surface of the air outlet 11 and the lower edge of the air outlet 12 are provided with a water-blocking step 13, and a water outlet 14 is provided in front of the water-blocking step 13.

[0037] This technical solution guides condensate or external splash water generated during the drying process along the bottom of the tank to the outlet 14, thereby preventing water from directly flowing into the fan 27, electric heating element 28, and control components inside the base 1, reducing the risk of electrical short circuits and corrosion. The inclined bottom surface and directional air outlet 12 help control the outlet angle and speed of the hot air, reducing turbulence and ineffective loss of hot air at the outlet 12. Combined with optimized control of the fan 27 and heating element, this improves heat utilization efficiency and energy consumption performance.

[0038] The base 1 is provided with a water outlet 15 that connects to the water outlet 14. The water outlet 15 is used to drain the water dripping from the clothes in the drying drum 26.

[0039] This technical solution allows the water outlet 15 to connect directly to the water outlet 14, enabling the direct discharge of water dripping from clothes inside the drying drum 26. This prevents water from accumulating in the air outlet 11 or the base 1, reducing the risk of corrosion and electrical malfunctions caused by water accumulation inside the machine. The water outlet 15 can be quickly connected to hoses, drain pipes, or collection containers, facilitating centralized drainage or closed-loop recycling in environments such as hotels, dormitories, or the outdoors, enhancing the equipment's adaptability and flexibility.

[0040] The bottom of the drying barrel 26 is provided with a detachable first isolation net 29, and the inner wall of the drying barrel 26 is provided with a plurality of vertically protruding support ribs 31 at intervals, and the support ribs 31 are provided with a detachable second isolation net 30.

[0041] This technical solution allows the first isolation net 29 and the second isolation net 30 to form two layers of space for storing clothes, increasing the efficiency of clothes drying. The isolation nets have a detachable structure, allowing users or after-sales personnel to easily remove them for cleaning or replacement, simplifying daily maintenance procedures and helping to maintain equipment hygiene and reduce the possibility of bacterial growth. The isolation nets prevent large water droplets and fibers from entering the lower air duct or base 1, reducing contamination and corrosion of key electrical components such as the impeller of the fan 27 and the electric heating element 28, thereby extending the life of key components and reducing maintenance frequency.

[0042] The base 1 is equipped with ultraviolet disinfection lamps 16 that are electrically connected to the control components and the power supply 21. The ultraviolet disinfection lamps 16 are distributed on both sides of the bottom of the drying barrel 26.

[0043] This technical solution utilizes ultraviolet (UV) disinfection lamps 16 to sterilize the surface of clothing and the walls of the drying drum 26, effectively inactivating bacteria, viruses, and mold spores. This improves the hygiene level of both the clothing and the drying drum 26, making it particularly suitable for scenarios with high hygiene requirements, such as those involving underwear and infant clothing. The UV lamps, combined with the hot air generated by the fan 27 and electric heating element 28, enhance the microbial inactivation rate through a synergistic effect of heat and light, shortening the disinfection time and enabling the washer-dryer process to perform disinfection simultaneously with drying.

[0044] The base 1 is also equipped with a drive motor 17 that is electrically connected to the control components and the power supply 21. The drive motor 17 is rotatably connected to a drive shaft 18. A washing impeller 19 located at the bottom of the washing tub 25 is fixedly connected to the drive shaft 18. The washing impeller 19 is driven by the drive motor 17 to rotate forward and backward to wash clothes.

[0045] This technical solution arranges the drive motor 17 within the base 1 and directly drives the washing impeller 19 via the drive shaft 18. The power transmission path is short and the structure is simple, which is beneficial for the miniaturization and weight control of the entire machine, making it easy to carry and install. The impeller efficiently generates circulating water, enhancing the contact between detergent and the surface of clothes, achieving good cleaning results with less water. Combined with controllable motor speed and timer control, energy consumption is reduced. In use, water is simply added or poured into the washing tub 25; no external piping is needed to increase installation difficulty, making it more convenient to carry.

[0046] The base 1 has a mounting slot 20 at its bottom for mounting a power supply 21. The power supply 21 is fixedly installed in the mounting slot 20, and a removable cover plate 22 is installed on the mounting slot 20.

[0047] By fixing the power supply 21 in the mounting groove 20 at the bottom of the base 1 and adding a removable cover plate 22, the power supply 21 can be effectively protected from external impacts, splashes, dust and foreign objects, reducing the risk of short circuits, corrosion and failure, and improving the safety and reliability of the whole machine.

[0048] The base 1 is also provided with a heat dissipation groove 23 at the bottom.

[0049] Through this technical solution, the heat dissipation groove 23 provides more heat dissipation area and natural convection channels for the bottom of the base 1, which can more quickly carry the heat generated by the power supply 21, drive motor 17, fan 27 and electric heating element 28 out of the machine body, reducing the internal temperature. The more even heat dissipation of the base 1 can prevent heat from accumulating at the bottom, which would cause a decrease in the efficiency of the fan 27 / heating element, ensuring that the heating and air supply system operates stably at the set power, thereby maintaining the drying performance.

[0050] The control component includes a button 24 located on the side of the base 1, which is used to control the activation and deactivation of the functions of each component.

[0051] This technical solution enables convenient operation of "one-button washing and drying," "individual disinfection," or "energy-saving mode," reducing user setup complexity and optimizing energy management, achieving a good match between human-computer interaction and energy efficiency. Users can easily access the device while using and carrying it, and can complete the on / off and mode switching with one hand, improving interaction efficiency and ease of use.

[0052] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
