As shown in fig. 4 to 8 and 12, a weighing module 104 is provided in the main body part 100, and the weighing module 104 can detect the load of the wire rope 200 in real time. The weighing module 104 communicates with the control module 103, and the control module 103 sends a corresponding signal to the power module 101 by judging that the weighing module 104 detects the weight information, so that the power module 101 executes corresponding operation.
The control module 103 may receive the weight information of the weighing module 104, compare it with preset information, and convert it into command information for controlling the power module 101.
When the weighing module 104 detects that the load exceeds the preset maximum weight value, the control module 103 sends a signal of stopping the operation to the power module 101, so as to perform overweight protection on the clothes drying machine.
Meanwhile, when the weighing module 104 detects that the load is smaller than the weight of the clothes drying component 300, the control module 103 sends a signal for stopping the operation to the power module 101, so that the protection of the clothes drying machine when the clothes drying machine descends and meets resistance is realized.
As shown in fig. 5, the weighing module 104 includes a fixing frame 01, a pulley assembly 02, and a gravity sensor 03. The fixing frame 01 is used for installing the gravity sensor 03 and the pulley assembly 02. The pulley assembly 02 is used for allowing the steel wire rope 200 to pass through and steering the steel wire rope 200, and the pulley assembly 02 is subjected to a resultant force F of the loaded steel wire rope 200, so that the pulley assembly 02 is driven to move in the fixed frame 01 in a certain range along the direction of the resultant force F. The gravity sensor 03 is installed at the fixed frame 01 near the pulley assembly 02 along a direction perpendicular to the resultant force F, and is located at a side of the pulley assembly 02 far away from the steel wire rope 200.
That is, the loaded wire rope 200 drives the sheave assembly 02 to move in a direction close to the load cell; the pulley assembly 02 is subjected to the resultant force F of the steel wire rope 200 and acts on the gravity sensor 03 in a direction perpendicular to the resultant force F, so that the gravity sensor 03 is subjected to stress deformation. According to the force transmission principle, the direction of the pressure F1 applied to the gravity sensor 03 is consistent with the direction of the resultant force F of the steel wire rope 200 applied to the pulley assembly 02, and the pressure F1 applied to the gravity sensor 03 is the resultant force F of the steel wire rope 200.
The gravity sensor 03 transmits the detected value to the control module 103, and the control module 103 calculates the value through a built-in calculator, so that the load of the wire rope 200 can be obtained, and the weight of the aired object can be further obtained. Preferably, the control module 103 is composed of a single chip microcomputer and a peripheral circuit, and a calculation program is preset in the single chip microcomputer to process data transmitted by the gravity sensor 03, compare the data with preset information stored in the single chip microcomputer, and output instruction information for controlling the power module 101 when the value is too large or too small.
As shown in fig. 5-10, the fixing frame 01 is fixed on the metal end plates 1 at both ends of the clothes airing machine, and includes a U-shaped groove 013 formed by a bottom plate 011 and two side plates 012, the gravity sensor 03 and the pulley assembly 02 are located in the U-shaped groove 013 of the fixing frame 01, and the axis of the U-shaped groove 013 forms an angle of 45 degrees with the horizontal direction.
The pulley assembly 02 includes a pulley 021, a wheel carrier 022, and an axle 023. Preferably, the bottom of the wheel frame 022 is provided with a protrusion portion 022a matched with the force-receiving area 031 of the gravity sensor 03.
The pulley 021 is coupled to the wheel carrier 022 through the wheel shaft 023, the wire rope 200 led out from the driving module 102 extends horizontally to bypass the pulley 021 and turns to extend vertically after passing through the pulley 021, the lower end of the vertically extending wire rope 200 is coupled to the clothes drying component 300, that is, the resultant force F of the wire rope 200 to the pulley assembly 02 forms an angle of 45 degrees with the horizontal direction. Due to the angle arrangement, even if the steel wire rope 200 is lifted more smoothly, the assembly of each part of the weighing module is also facilitated.
The gravity sensor 03 is fixed on the bottom plate 011 of the fixed frame 01 and is opposite to the bottom of the wheel carrier 022. Preferably. The bottom plate 011 is provided with a through area matched with the gravity sensor 03, and the gravity sensor 03 is connected with the bottom plate 011 through a buckle.
Furthermore, the two side plates 012 are symmetrically provided with inclined grooves 014, so that the wheel shaft 023 passes through and the wheel shaft 023 can move in the inclined grooves 014, the extending direction of the inclined grooves 014 is the same direction as the direction of the resultant force F of the pulley 021 by the steel wire rope 200, in this embodiment, the direction of the inclined grooves 014 forms an angle of 45 degrees with the horizontal direction.
When the pulley assembly 02 is acted upon by the cable 200, it moves along the inclined groove 014 in the U-shaped groove 013 of the fixed frame 01, and the protrusion 022a of the wheel frame 022 acts on the force-receiving area 031 of the gravity sensor 03. Similarly, when the descending resistance-encountering steel wire rope 200 is loosened, the pulley assembly 02 moves away from the gravity sensor 03, and the deformation of the gravity sensor 03 is reduced.
Because the extending direction of the inclined groove 014 and the extending direction of the U-shaped groove 013 are the same as the direction of the resultant force F of the pulley 021 by the steel wire rope 200, the pulley assembly 02 does not collide and rub with the inclined groove 014 or the fixed frame 01 in the process of moving along the inclined groove 014, and the generation of a friction component force in the same direction as the direction of the pressure F1 applied to the gravity sensor 03 is avoided, so that the pressure F1 applied to the gravity sensor 03 is basically the same as the resultant force F, the detection interference factors of the whole weighing module 104 are reduced, and the measurement error is reduced and the accuracy is improved.
By providing this weighing module 104 on the clothes drying machine, as shown in fig. 12, the clothes drying machine may also be provided with a drying control system based on the change in the weight of the aired clothes. The clothes hanger further comprises a drying module 105, the control module 103 is connected with the drying module 105, and the control module 103 sends a corresponding signal to the drying module 105 by judging that the weighing module 104 detects the weight information.
Preferably, the drying module 105 comprises a fan, and may also be provided with a heating module. The drying module 105 may be built in the main body part 100, or may be a lower structure.
The drying module 105 adjusts the corresponding power gear according to the weight of the aired clothes detected by the weighing module 104.
As shown in fig. 13, specifically, during the use of the laundry rack, the weighing module 104 detects the load weight of the steel wire rope 200 in real time and transmits the load weight to the control module 103 for corresponding processing. When the control module 103 sends an instruction to perform air drying/drying, the control module 103 collects the first weight information in the corresponding operation area and stores the first weight information in the corresponding memory. When the drying module 105 performs air drying/drying, at a preset time point, the control module 103 collects weight information of a corresponding time point and compares and processes the weight information.
More specifically, at the first preset time point, the control module 103 first retrieves the first load weight information, calculates the first load weight information and the load weight information at the time point, and compares the calculated value with the first-level set value. And when the lightening rates of the two are greater than the first-level set value, controlling to finish the air drying operation, otherwise, performing secondary judgment.
A secondary set value corresponding to the power gear of the drying module 105 is set in the secondary judgment, and the control module 103 sends different power gear starting instructions to the drying module 105 by comparing the operation value with the secondary set value, and continues the drying operation.
At the next time point, the control module 103 retrieves the load weight information at the previous time point, compares the load weight information between the two adjacent time points, determines the program according to the above method, compares the load weight information again, and outputs a control instruction for corresponding control.
In this way, when the drying module 105 performs air drying/drying, the weighing module 104 detects the weight of the load in real time, the control module 103 calculates the weight change condition of the load, and determines whether the corresponding power gear needs to be adjusted according to the weight change condition of each time period of the load, so that the drying quality and efficiency of the clothes drying machine are improved, and the intelligent degree of the clothes drying machine is improved.
