The operation principle of the telescopic wheel supporting assembly 1 of the drum washing machine of the present utility model will be briefly described with reference to fig. 3, 4 in conjunction with fig. 1 and 2. Fig. 3 is a schematic view of the working principle of the telescopic wheel supporting assembly (the retracted state of the wheel structure) of the drum washing machine according to the present utility model; fig. 4 is a schematic view of the operation principle of the telescopic wheel supporting assembly (the extended state of the wheel structure) of the drum washing machine of the present utility model.
As shown in fig. 3 and 4, when the drum washing machine needs to be moved, the driving motor 21 drives the connecting rod 22 to act through the rotary rod (the rotary member 23), the connecting rod 22 drives the plunger 311 of the first hydraulic cylinder 31 connected with the connecting rod 22 to move leftwards in the cylinder barrel, the volume of the first liquid bag 313 in the cylinder barrel is compressed to generate positive pressure, and then the hydraulic oil 5 in the first liquid bag 313 is split into each slave tube 332 along the master tube 331 and flows to the second hydraulic cylinder 32, the volume of the second liquid bag 323 in the second hydraulic cylinder 32 is compressed to generate positive pressure, so that the second liquid bag 323 pushes the plunger in the second hydraulic cylinder 32 to extend outwards, and at the moment, the wheel structure 4 connected with the plunger 321 of the second hydraulic cylinder 32 extends to lift the supporting foot at the bottom of the machine body away from the ground, and at the moment, the drum washing machine can be easily pushed to move. After the movement is completed, the electric driving mechanism 2 drives the rotating member 23 to drive the connecting rod 22 to reversely move, the connecting rod 22 drives the plunger 311 of the first hydraulic cylinder 31 connected with the connecting rod 22 to move rightwards in the cylinder barrel, the movement stretches the volume of the first liquid bag 313 in the cylinder barrel to generate negative pressure, and then the hydraulic oil 5 of the second liquid bag 323 further flows back into the first liquid bag 313 after converging from the pipe 332 to the main pipe 331, and then the volume of the second liquid bag 323 of the second hydraulic cylinder 32 is stretched to generate negative pressure, so that the second liquid bag 323 drives the plunger in the second hydraulic cylinder 32 to retract inwards, and at the moment, the wheel structure 4 connected with the plunger 321 of the second hydraulic cylinder 32 also retracts to enable the supporting bottom leg at the bottom of the machine body to fall to the ground, thereby playing a supporting and fixing role on the washing machine.
As can be seen from the above description, the first hydraulic cylinder 31 is driven by the driving motor 21 to act, and then the first hydraulic cylinder 31 drives the second hydraulic cylinder 32 to act through the infusion pipeline 33 to control the wheel structure 4 to extend or retract, so that the drum washing machine of the utility model not only greatly simplifies the structure of the telescopic wheel supporting assembly 1, but also enables the driving motor 21 and the hydraulic cylinder or the infusion pipeline 33 to be freely arranged in the drum washing machine, thereby greatly increasing the arrangement flexibility of the drum washing machine and improving the space utilization rate. In addition, the driving motor 21 effectively reduces or even avoids the leakage of the hydraulic oil 5, greatly reduces the failure rate of the drum washing machine and improves the use experience of users. Further, the arrangement of the first liquid bag 313 and the second liquid bag 323 ensures the tightness of the first hydraulic cylinder 31 and the second hydraulic cylinder 32 and the flow tightness of the hydraulic oil 5 among the first hydraulic cylinder 31, the second hydraulic cylinder 32 and the infusion pipeline 33, thereby prolonging the service life, and reducing or even avoiding the occurrence of the leakage phenomenon of the hydraulic oil 5. By the arrangement mode that the diameter of the cylinder barrel 312 of the second hydraulic cylinder 31 is smaller than that of the cylinder barrel 322 of the second hydraulic cylinder 32, the first hydraulic cylinder 31 can generate larger hydraulic pressure when the same driving motor 21 is used, the transmission effect is enhanced, and the extending and retracting efficiency of the wheel structure 4 is ensured; or on the premise of ensuring the same hydraulic pressure, a smaller-sized driving motor 21 can be selected, so that the occupied space of the driving motor 21 and the production cost of the drum washing machine are effectively reduced.
It will be appreciated by those skilled in the art that the foregoing embodiments are merely illustrative of the principles of the present utility model and are not intended to limit the scope of the utility model, which is defined by any reasonable modification of the structure of the utility model to adapt it to a more specific application without departing from the principles of the utility model. For example, the drive motor 21 may also be replaced by an electric cylinder or air cylinder, in which case the connecting rod 22 is correspondingly connected to the piston of the electric cylinder or air cylinder; for another example, the number of second hydraulic cylinders 32, the number of wheel structures 4, and the number of support feet may all be adjusted based on the particular application scenario. As another example, although described in connection with hydraulic oil 5, it is apparent that the present utility model may be used with other forms of fluid having a viscosity so long as the fluid itself does not cause corrosion to the hydraulic cylinders, the oil line 33, and the fluid bladder.

The control principle of the present utility model will be described with reference to fig. 8 and 9. Fig. 8 shows control logic of the drum washing machine upon receiving a command for the wheel structure to be extended, and fig. 9 shows control logic of the drum washing machine upon receiving a command for the wheel structure to be retracted.
As shown in fig. 8, when the communication module receives an instruction of extending the wheel structure, the detection module detects the resistance temperature value T of the driving motor, then judges the resistance temperature value T and the temperature threshold Tc, when the resistance temperature value T is greater than or equal to the temperature threshold Tc, it proves that the driving motor is overheated and needs to be stopped for protection, at this time, the control module controls the motor to stop working and send out an audible and visual alarm (if the drum washing machine is provided with an audible and visual alarm device), then after the duration T, the detection module re-executes the resistance temperature value T of the driving motor and compares the resistance temperature value T with the temperature threshold Tc, and when the resistance temperature value T is less than Tc, the driving motor is powered, the driving motor drives the transmission mechanism to act, and the wheel structure extends out of the machine body smoothly.
As shown in fig. 9, when the communication module receives a command for retracting the wheel structure, the control module firstly supplies power to the driving motor, the wheel structure starts to retract in the machine body, in the retracting process, the detection module detects the running current value I of the driving motor, then judges the running current value I and the current threshold Ic, when the running current value I is greater than or equal to the current threshold Ic, the fact that the wheel structure is clamped in the retracting process is proved, if the trunk of a human body is possibly clamped between the ground and the machine body, the driving motor receives resistance to increase, the current value is increased instantaneously, at the moment, the control module controls the motor to stop working and sends out an audible and visual alarm (if the drum washing machine is provided with an audible and visual alarm device), then the running current value I is continuously detected, and when the current value I returns to the normal range, the control module releases the audible and visual alarm and supplies power to the driving motor, and the driving motor drives the transmission mechanism to act, so that the wheel structure is successfully retracted into the machine body.
As can be seen from the above description, the present utility model can determine whether the wheel structure is extended and retracted from a hindrance (e.g., whether a foreign object is stuck between the wheel structure and the machine body or whether a human body is stuck between the machine body and the ground, etc.) by detecting the operation parameters of the driving module in the process of controlling the extension and retraction of the wheel structure by the driving module, and can realize the intelligent lifting of the wheel structure by controlling the driving module to stop working when the hindrance is encountered, thereby protecting the driving module and personal safety and improving the safety of the extension and retraction process of the wheel structure. That is, through the above-mentioned setting method, solved current gyro wheel pushing down machine and had the problem that the security is low, promoted clothing treatment facility's security, improved user's use experience, be fit for extensive popularization.
Finally, it should be noted that although the above preferred embodiments are described by taking a drum washing machine as an example, it is not intended to limit the scope of the present utility model, and those skilled in the art will appreciate that the present utility model can be applied to other laundry treatment apparatuses requiring movement, such as pulsator washing machines, clothes dryers, shoe washing machines, or drum-pulsator washing machines, in addition to drum washing machines.
