Description

Technical Field

[0001] This invention belongs to the technical field of clothing processing devices, specifically relating to a clothing processing device with upper and lower double rollers. Background Technology

[0002] As people's living standards continue to improve, they are increasingly pursuing a safe and comfortable clothes drying experience. The current market trend is shifting from single-drum drying to multi-drum independent drying. This is because the heat exchange system of drying includes air ducts and heat exchange components. The air ducts mainly transport dry hot air and humid cold air from the heat exchange components, allowing the air to circulate in the heat exchange system to achieve the effect of drying clothes. The existing multi-drum clothes drying devices on the market require multiple air ducts, such as front upper air duct, front lower air duct, rear upper air duct, and rear lower air duct. This results in a complex overall structure, increased size, higher cost, and heavier weight for the clothes drying device.

[0003] There are currently no solutions to the technical problems existing in the aforementioned garment processing devices; therefore, there is an urgent need to find effective solutions to address these issues. Summary of the Invention

Figure 1 Extending in the direction shown, the longitudinal direction is the front-to-back direction of the first washing tub 2 and the second washing tub 3; specifically, the upper end of the upper air duct is fixedly connected to the upper crossbeam 6, and the air distribution mechanism is fixedly connected to the middle crossbeam 5; the upper air duct has an air inlet at the end near the air distribution mechanism and an air outlet at the end away from the air distribution mechanism, the lower air duct has an air inlet at the end near the air distribution mechanism and an air outlet at the end away from the air distribution mechanism. This design increases the stability of the air duct and also increases the space on the drum body where counterweights can be placed; the air distribution mechanism has one air inlet and two air outlets. The air inlet of the air distribution mechanism is connected to the air outlet of the rear air duct for air intake; the air distribution mechanism has two air outlets, wherein the first air outlet is connected to the air inlet of the upper air duct, and the air outlet of the upper air duct is flexibly connected to the first washing tub 2; the second air outlet is connected to the air inlet of the lower air duct, and the air outlet of the lower air duct is flexibly connected to the second washing tub 3; the clothing processing device provided by the present invention fixes the front air duct 4 to the frame, specifically at the connecting part, so that the front air duct 4 has a fixed support, increasing the stability of the air duct, effectively utilizing the space on the frame, reducing the safety gap required between the air duct and the frame, and simplifying the fixing structure of the air duct.

[0041] Preferably, in combination with the above schemes, such as Figure 1 As shown, in this embodiment, the air distribution mechanism is arranged corresponding to the space between the first washing tub 2 and the second washing tub 3; the rear air duct extends from the front side to the rear side of the first washing tub 2 and the second washing tub 3 within the space; specifically, refer to... Figure 1 As shown, the fixed connection direction between the upper air duct and the upper crossbeam 6 and the fixed connection direction between the air distribution mechanism and the middle crossbeam 5 are both the longitudinal direction of the frame.

[0042] Preferably, in conjunction with the above scheme, in this embodiment, a heat exchange component is provided on the rear air duct, and the air outlet of the heat exchange component is opposite to and connected to the air inlet of the air distribution mechanism; specifically, the heat exchange component is a heat pump module.

[0043] Preferably, in combination with the above schemes, such as Figure 1 As shown, in this embodiment, the length of the upper air duct is greater than the length of the lower air duct.

The vertical section and the horizontal section form a curved structure that can hold the first washing tub. In this embodiment, the "height direction of the vertical beam" refers to... Figure 1 Based on the vertical direction, the horizontal direction is based on... Figure 2 The horizontal axis is used as the reference.

[0044] Preferably, in combination with the above schemes, such as Figure 1 , Figure 3as well as Figure 7 As shown, in this embodiment, a counterweight 10 is also provided on the outer peripheral wall of the first washing tub 2, and the direction of the counterweight 10 is opposite to the direction of the upper air duct holding the first washing tub 2. Specifically, each washing tub includes an outer tub and an inner tub, the inner tub is set inside the outer tub and can rotate inside the outer tub. Further, a counterweight 10 is fixed on the outer wall of the outer tub. Further, fixing the front air duct 4 to the frame can increase the space on the tub to place the counterweight, and a counterweight 12 is added to one end of the tub. Since the front air duct 4 is fixed to the frame, there is a reserved space between the tub and the front air duct 4 to place the counterweight, so that the vibration of the whole machine during operation is effectively improved, and the noise reduction effect is achieved. By adopting the above structural design, by fixing the air duct to the frame, the space on the tub to place the counterweight is increased, so that the vibration of the whole machine during operation is effectively improved, and the noise reduction effect is achieved.

Specifically, the upper door seal 7 is located at the top of the first washing tub 2, and the lower door seal 8 is located at the top of the second washing tub 3. This allows the drying gas to be introduced into the tub from top to bottom, improving the drying effect. Specifically, the connecting component includes a middle crossbeam 5, which is located between the first washing tub 2 and the second washing tub 3, thereby improving the stability of the air duct fixing structure between the two washing tubs.

[0056] Preferably, in combination with the above schemes, such as Figures 1 to 7As shown, in this embodiment, the clothing processing device is a dryer or a washing machine. By adopting the above solution, a single air duct structure can be designed to connect the two drums, thereby achieving the drying effect separately. With the above solution, by fixing the air duct to the frame, one end of which is connected to the heat exchange component in the heat exchange system, and the other end is connected to the drum through a flexible door seal with pleats, the air duct will not move with the movement of the drum, increasing reliability and increasing the space on the drum where counterweights can be placed. This effectively improves the vibration of the whole machine during operation, achieving effects such as noise reduction.

[0057] The upper and lower double-drum clothing processing device provided by the present invention can effectively utilize the space of the whole machine while ensuring that the air duct can effectively transmit the drying air volume. Moreover, the fixed structure of the air duct is relatively simple, with good stability and adaptability, which can simplify the fixed structure of the air duct and reduce costs.

[0058] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the present invention. Any person skilled in the art can make many possible variations and modifications to the technical solution of the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of the present invention without departing from the scope of the present invention are within the protection scope of the present invention.
