Fig. 1 to 4 show a clothes drying machine 100 with a lower drying assembly according to the present embodiment, which includes a main unit 110, a lifting assembly 120, a drying rod assembly 130 and a drying assembly 140. A motor (not shown) is disposed in the main unit 110, and the airing bar assembly 130 is connected to the lower portion of the main unit 110 through the elevating assemblies 120 at both ends.
The motor drives the lifting assembly 120 to drive the airing bar assembly 130 to ascend and descend, and in particular, the lifting assembly 120 includes a wire rope (not shown) and a folding frame 121, one end of the wire rope is wound on a reel (not shown) which is disposed in the main unit 110, typically, in the vicinity of the motor, and the motor is rotated forward or reverse to drive the reel to rotate forward or reverse to wind and unwind the wire rope to drive the airing bar assembly 130 to ascend or descend. The folding frame 121 folds or unfolds as the pole assembly 130 rises or falls to maintain the stability of the pole assembly 130.
The drying assembly 140 is connected under the drying bar assembly 130 through the connection bars 141 at both ends, and the drying assembly 140 can be lifted and lowered along with the drying bar assembly 130 when the drying bar assembly 130 is lifted and lowered. The drying assembly 140 includes an air outlet (not shown), a heater (not shown) and a fan (not shown), in the drying mode, both the heater and the fan are turned on, the fan sucks the outside air into the drying assembly, the air is heated by the heater and becomes warm air flow, and the warm air is sent out from the air outlet to dry the clothes suspended on the drying rod assembly 130 above the warm air flow, so that the drying assembly is called a "lower-mounted" drying assembly clothes drying machine.
The specific installation connection mode and the specific working mode of the lower drying assembly 140 can be referred to the specific implementation modes of the lower drying module connection mechanism and the clothes airing machine disclosed in the patent with the publication number CN108342887B, and are not described herein.
The drying bar assembly 130 is lowered as shown in fig. 1, and the connection rod 141 is unfolded to suspend the drying assembly 140 under the drying bar assembly 130. The drying assembly 140 is positioned at the leg of the user because the drying assembly 130 is lowered to allow the user to reach the laundry hanging on the drying assembly 130 by hand, and the drying assembly 140 is positioned at the shoulder of the user, and the vertical distance between the drying assembly 140 and the drying assembly 130 is at least greater than the length of the laundry.
It is conceivable that if the drying mode is in this case, i.e. the state in which both the heater and the blower are on, the temperature of the surface of the drying assembly is high, and the user is easily scalded. Therefore, a primary lock is required to ensure that the drying function is enabled when the drying bar assembly 130 is raised to the upper limit.
Further, as shown in fig. 2, the drying rod assembly 130 enters a drying mode and starts a drying function when the upper limit is reached, after the drying mode is finished, if the heater and the fan are synchronously turned off, the surface of the drying assembly 140 has a residual heat temperature, and at this time, if the user directly descends the drying rod assembly 130 and collects clothes, the user is also easy to be scalded by the residual heat on the surface of the drying assembly 140. Therefore, a heat dissipation mode and a secondary lock, which are matched with each other, are required to be provided, so that the drying assembly 140 is ensured to perform residual heat dissipation, and the drying rod assembly 130 can be lowered after the heat dissipation function is finished.
The anti-scalding protection system 200 of the underneath type clothes drying machine is arranged in the underneath type clothes drying machine 100, and is used for executing the anti-scalding protection method of the underneath type clothes drying machine, so as to realize the primary locking, the heat dissipation mode and the secondary locking, and prevent a user from being scalded by the underneath type clothes drying machine 140 in the use process.
The anti-scalding protection system 200 of the underneath type clothes drying machine with the drying assembly provided by the embodiment comprises a power supply, a controller 210 and a drying assembly control circuit 220. The power supply not only provides power for the operation of the motor, but also provides power for peripheral electrical components such as the controller 210 and the drying assembly control circuit 220.
In this embodiment, the controller 210 adopts an MCU microcontroller, but it is needless to say that other kinds of controllers such as an integrated chip or devices having a processor such as a microcomputer may also be adopted. For convenience of description and understanding, the following describes a preferred anti-scalding protection method for a clothes drying machine with a lower drying assembly according to this embodiment, and specifically describes a system on which the method is implemented.
