[0091] The preferred embodiments of the present application will be described in detail below with reference to the attached drawings. Those skilled in the art will appreciate that the description is merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present application.
[0092] It should be noted that similar reference numerals refer to similar items throughout the attached drawings, and once an item is defined in one drawing, it can not be further defined and explained in subsequent drawings.
[0093] As Figure 1 and Figure 2 shown, the door rotating opening and closing clothes treatment equipment 100 includes a main machine 10 with an inner cavity, a door body 20 and a driving mechanism 30. The inner cavity of the main machine 10 is used to accommodate clothes, and the door body 20 is movably connected to the main machine 10. The driving mechanism 30 is used to drive the opening and closing of the door body 20.
[0094] Further, the front wall of the main machine 10 is provided with an opening 12 communicating with the inner cavity, and the door body 20 includes a front panel 21 and a boss 22 inside the front panel 21. The boss 22 is embedded into the inner cavity through the opening 12. A sealing assembly, such as a sealing ring, is provided between the boss 22 and the opening 12 to ensure the sealing of the opening.
[0095] In addition, in view of the existence of the boss 22 and the demand for the compact cabinet type clothes treatment system developed by our company, the present application changes the opening mode of the door body 20, which rotates to one side based on the connection point with the main machine 10 to open the opening 12. The specific implementation is as follows:
[0096] As Figure 4 and Figure 5 shown, the upper end of the front panel 21 is provided with a connecting arm 14. The driving mechanism 30 is provided on one side of the top wall of the main machine 10 and extends along the width direction of the top wall.
[0097] It is to be noted that the connecting arm 14 is arranged on the upper end of the front panel 21 close to the driving mechanism 30. The door body 20 is in a circular cross section, and the connecting arm 14 is in a "fan shape", with the wide arc end of the "fan face" being connected to the circular outer edge of the door body 20, and the narrow handle end of the "fan face" being connected to the driving mechanism 30 for driving. The connecting arm 14 further comprises a vertical extension wall t1 cut on the outer edge of the circular door body 20, and an arc wall t2 in arc transition with the circular door body 20, so that the door body 20 and the connecting arm 14 are in a coherent "water drop shape" as a whole, thereby ensuring the stability and integrity of the transmission relationship between the connecting arm 14 and the door body 20 under driving.
[0098] More specifically, as shown in Figures 6 to 12 the driving mechanism 30 comprises an electric push rod 31, a follower shaft 32, a fixed seat 33 and a shaft pin 34. In assembly, the fixed seat 33 is provided with a shaft sleeve 35, and the shaft pin 34 extends into the inner cavity of the shaft sleeve 35 through the shaft sleeve 35. The outer peripheral wall of the follower shaft 32 is provided with a track groove h for the insertion of the shaft pin 34. The shaft pin 34 moves forward and backward along the track groove h to meet the two movement modes of forward and backward movement and rotation of the door body 20. Specifically as follows:
[0099] The driving rod 31a of the electric push rod 31 is movably connected to the tail end of the follower shaft 32 through a rotating joint 40, and the follower shaft 32 is connected to the connecting arm 14 after passing through the shaft sleeve 35. The track groove h comprises a straight groove h1 distributed along the axial direction and a spiral groove h2 at the rear end of the straight groove h1.
[0100] In actual work, when the electric push rod 31 pushes the follower shaft 32 to move forward, the movement track of the shaft pin 34 in the track groove h comprises a first movement track corresponding to the straight groove h1 and a second movement track corresponding to the spiral groove h2.
[0101] The first movement track is that the shaft pin 34 moves from the front starting point to the rear end point of the straight groove h1, at which time the door body 20 with the boss 22 moves outward (the linear movement mode of the door body 20), until the boss 22 on the front panel 21 is moved out of the inner cavity of the main machine.
[0102] The second movement track is that the shaft pin 34 moves from the front starting point to the rear end point of the spiral groove h2, and the door body 20 continues to move outward in rotation (the rotation movement mode of the door body 20, in which movement mode, the door body 20 still has a short path of outward linear movement), while the door body 20 rotates to one side away from the opening 12 of the main machine.
[0103] In addition, it is to be noted that, as Figure 9As shown, the rotary joint 40 includes a mandrel 41 at the front end of the drive rod 31a of the electric push rod 31 and a connecting groove 42 at the rear end of the follower shaft 32, the mandrel 41 extends into the connecting groove 42, and the connecting groove 42 is fitted with a bearing 43; the mandrel 41 can rotate relative to the connecting groove 42.
[0104] Among them, the bearing 43 in the rotary joint 40 includes a plain thrust bearing and a deep groove ball bearing, so that the drive input end of the mandrel 41 can bear the single-direction axial load, and the drive output end of the mandrel 41 can bear the radial load, greatly improving the position stability of the rotary joint 40 itself. Meet the double driving mode of the driving mechanism 30 which needs linear driving and rotary driving.
[0105] It should be noted here that the above technical solutions of the rotary joint 40 aim to achieve the following technical purposes: 1. When the electric push rod 31 only drives the follower shaft 32 to move linearly, the cooperation of the shaft pin 34 and the linear groove h1 and the spiral groove h2 can still realize the linear outward movement of the door body 20 and the rotation accompanied by the outward movement; At this time, the rotary joint 40 which simultaneously includes a plain thrust bearing and a deep groove ball bearing provides the function of bearing radial load, which aims to compensate for the radial deviation that may occur when the door body 20 rotates, and meets the needs of frequent rotation of the door body 20. 2. When the electric push rod 31 is driven linearly and rotationally, the cooperation of the spiral groove h2 and the shaft pin 34 plays a more important role in guiding the activity direction (the force is mainly output by the drive rod 31a), and at this time the function of bearing radial load provided on the rotary joint 40 aims to bear the torque under the rotary driving of the drive rod 31a.
[0106] Preferably, the driving mechanism 30 is arranged on one side of the top of the main machine 10, the rear end of the top of the main machine 10 is provided with a base 50, the rear end of the electric push rod 31 is fixed on the base 50, and the fixed seat 33 is arranged on the front side of the top of the main machine 10.
[0107] More preferably, the opening of the front wall of the main machine 10 is provided with a recessed part 17, and the inner side of the front panel 21 of the door body 20 can be embedded into the recessed part 17.
[0108] A locking assembly is arranged between the door body 20 and the main machine 10, specifically, two lock catches are arranged on the recessed part 17, and a lock pin matched with the lock catch is arranged on the front panel 21.
[0109] Preferably, the length of the linear groove h1 in the embodiment is 8-10CM, and the axial length of the spiral groove h2 is 4-6CM.
[0110] In summary, the door 20 opening process in this embodiment includes two movement modes: a linear movement mode and a rotational movement mode. In the linear movement mode corresponding to the first movement trajectory, the pin 34 moves from the front starting point to the rear ending point of the linear groove h1. At this time, the door 20 with the boss 22 moves outward (the linear movement mode of the door 20) until the boss 22 on the front panel 21 is removed from the inner cavity of the main unit. Secondly, in the rotational movement mode corresponding to the second movement trajectory, the pin 34 moves from the front starting point to the rear ending point of the spiral groove h2. The door 20 continues to rotate outward (the rotational movement mode of the door 20; in this mode, the door 20 still involves a short-path outward linear movement), while simultaneously rotating away from the main unit opening 12.
[0111] In linear operation mode, the door 20 moves outward by 8-10 cm; in rotary operation mode, the door 20 extends outward by 4-6 cm. That is, in this embodiment, the total linear distance of the door 20's axial outward movement is controlled at 12-16 cm, effectively reducing the distance the door 20 moves in depth.
[0112] In this embodiment, the specific steps of the door opening and closing method of the clothing processing device 100 are as follows:
[0113] A: The process of the door opening:
[0114] First step A1: As follows Figures 10 to 11 As shown, when the electric push rod 31 is activated, the drive rod 31a of the electric push rod 31 pushes the follower shaft 32 forward a first distance. The shaft pin 34 moves from the front starting point to the rear ending point of the straight groove h1. At this time, the door body 20 with the boss 22 moves outward until the boss 22 on the front panel 21 is removed from the inner cavity of the main unit 10, and the front panel 21 is in the first position. This step is intended to move the boss 22 of the door body 20 outward a certain distance so that it is misaligned with the front wall of the main unit 10 in the front-back direction, thereby allowing the door body 20 to perform the rotation action in the next step.
[0115] Step A2: As follows Figures 11 to 12 As shown, the drive rod 31a of the electric push rod 31 continues to push the follower shaft 32 forward a second distance, and the shaft pin 34 moves from the front starting point to the rear ending point of the spiral groove h2. The door body 20 continues to move outward in a rotating manner, while simultaneously rotating away from the opening 12 of the host 10, until the opening 12 of the host 10 is fully open and the front panel 21 is in the second position. In this step, the door body 20 rotates to open the opening while continuing to move outward until the opening 12 of the host 10 is fully open.
