Description

Technical Field

[0001] The invention relates to a component used in a clothes drying machine, in particular to a single-column lifting power supply structure and a clothes drying machine. Background Art

[0002] The main box of the clothes drying machine and the clothes drying cross bar are two relatively movable parts. The main box of the clothes drying machine does not move, while the clothes drying cross bar moves up and down. Therefore, if a relatively long electric wire is hung from the clothes drying machine to supply power to the electrical components of the clothes drying cross bar, it will affect the appearance.

[0003] Patents CN203212891U and CN208235178U both disclose detachable power supply mechanisms. Patent CN208235178U describes a scheme whereby power is supplied to the drying module by connecting a first power port on the underside of the main unit to a second power port on the clothes drying rack. In layman's terms, there's a socket on top and a plug on the bottom, and once the two connect, power is supplied.

[0004] In this design, firstly, the electric shock structure is exposed and unsafe, and secondly, there is no signal device. That is to say, once the top is raised, it is directly connected to the 220V power supply, which will damage the probe, which is not what the customer needs. Summary of the Invention

[0005] The present invention addresses the deficiencies in the prior art and provides a single-column lifting power-taking structure and a clothes drying machine that are highly safe and signal-controlled.

[0006] In order to solve the above technical problems, the present invention is solved through the following technical solutions: a single-column lifting power supply structure, an electric shock component installed above the clothes drying cross bar, which supplies power to the drying module, a switch component fixed on the lower surface of the clothes drying main box, which provides a signal for the lifting and lowering of the clothes drying cross bar, and a connecting component connecting the electric shock component and the switch component; the electric shock component includes a probe for conduction, the connecting component includes an electric control board connected to a power supply and a movable plate for fixing the electric control board, a top rod part is provided on the movable plate, and the switch component includes a signal switch; after the probe rises, it contacts the electric control board and pushes the movable plate and the top rod part thereon to move upward, and the top rod part presses the signal switch.

[0007] The movable plate also includes a flat plate portion, a first electric control board hole for installing the electric control board is provided in the center of the flat plate portion, and the push rod portion is provided on the upper surface of the side corner of the flat plate portion; the switch assembly also includes an upper sheet metal seat for fixing the signal switch and a lower sheet metal seat installed on the clothes drying main box, the upper sheet metal seat is installed on the lower sheet metal seat, and a first push rod hole is provided on the lower sheet metal seat, and the push rod portion presses the signal switch after passing through the first push rod hole.

[0008] The electric shock component further includes a protective sleeve, a probe spring, a copper screw, and a probe seat. A step is provided on the probe. The probe spring is arranged between the step and the copper screw. The copper screw is in contact with the electronic control board. The probe is arranged in a telescopic cavity formed by the protective sleeve and the probe seat. The probe seat is installed on the drying crossbar part.

[0009] The connection component further includes a connection seat. The connection seat includes a base plate, side seat plates, and four seat support columns. The seat support columns are installed on the lower sheet metal seat. A second electronic control board hole matching the electronic control board is provided at the center of the base plate, and a second ejector rod hole matching the ejector rod part is provided on the side.

[0010] The connection component further includes an insulating plate. A third electronic control board hole matching the electronic control board is provided at the center of the insulating plate; a set of return springs is arranged between the insulating plate and the movable plate.

The inner hook is fixed on the electronic control board; a first buckle hole is provided on the insulating plate, and a second buckle hole is provided on the connection seat. The outer hook passes through the first buckle hole and is arranged in the second buckle hole.

[0012] Compared with the prior art, the present invention has the following beneficial effects: An electric shock component is provided, so that the drying module of the drying crossbar part no longer needs to be powered by a hanging power cord; A switch component is provided. When the drying crossbar part rises to the top position, signal instructions such as power supply or heating are sent out; The connection component changes the hard contact mode between the electric shock component and the switch component, and adopts a third-party soft contact. During the rising process of the drying crossbar part, through the movable plate and the return springs, the impact force of the electric shock component on the switch component is reduced; An ejector rod part is provided on the side, creating more heat dissipation space to ensure the heat dissipation of the electronic control board.
