[0038] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.
[0039] like Figure 1-8 As shown, the following embodiment discloses a soaking timer capable of rapid on and off.
[0040] A soaking timer capable of rapid on and off, comprising:
[0041] Housing 100;
[0042] The escape wheel mechanism 200 has a stable movement cycle;
[0043] The timing main shaft 300 is passed through the housing and is sleeved with a soaking wheel set 400 that can rotate with the timing main shaft 300;
[0044] The washing wheel assembly 500 is driven by the escapement wheel mechanism 200 and rotates along with the timing spindle 300;
[0045] The washing wheel assembly 500 includes at least one washing cam 510 passing through the rotating shaft 520, and the washing cam 510 is provided with a first quick-break structure, which is used to drive the two reeds in the washing mode to quickly contact or disconnect;
[0046] The soaking wheel assembly 400 includes a first soaking cam 410 and a second soaking cam 420 which are sequentially mounted on the timing main shaft 300. The first soaking cam 410 and the second soaking cam 420 are provided with a second quick-break structure, and the second quick-break structure is used to drive the two reeds of the washing mode to quickly contact or disconnect.
[0047] The above is the basic solution of this embodiment.
[0048] Reference Figure 1 As shown, the timing main shaft 300 drives the escapement wheel mechanism 200, transmits the washing wheel set 500 and the soaking wheel set 400, and controls the washing state of the washing machine.
[0049] In the washing wheel assembly 500, the washing mode is controlled by the washing cam 510 on the two reeds. When the two reeds are in contact, the washing mode is turned on, and when the two reeds are separated, the washing mode is stopped.
[0050] In this embodiment, the washing cam 510 can be set to multiple, and according to the washing machine mode requirements, a strong washing mode, a light washing mode, etc. are set, and each mode is provided with a corresponding cam and a reed;
[0051] In the soaking wheel assembly 400, the first soaking cam 410 and the second soaking cam 420 control two reeds. Similarly, when the two reeds are in contact, the soaking mode is turned on, and when the two reeds are separated, the soaking mode is stopped.
[0052] In the present embodiment, since each mode has a set time, usually in minutes, and multiple soaking modes or washing modes are set during one rotation of the cam, the two reeds will undergo multiple contacts and disconnections. If the contact or disconnection speed between the reeds is slow, there will be a hidden danger of multiple sparks. In the present embodiment, a first quick-break structure and a second quick-break structure are provided so that the two reeds for the washing function and the two reeds for the soaking function can be quickly connected and disconnected to avoid the possibility of sparks.
[0053] The Chinese utility model patent with authorization announcement number CN208460662U discloses an immersion timer, which includes the structure and use of an escape wheel. The use and function of the escape wheel mechanism 200 in this embodiment are consistent with those in the prior art and will not be repeated again.
[0054] The soaking wheel set 400 and the washing wheel set 500 are both provided with gears for conducting connection with the escapement wheel mechanism 200 .
[0055] In this embodiment, the first quick-break structure is a two-layer wheel cam arranged radially on the washing cam 510, and the two layers of wheel cams are staggered.
[0056] Reference Figure 2 As shown, the two layers of wheel convexities are respectively set as the first wheel convexity 511 and the second wheel convexity 512, and the outer peripheries of the two wheel convexities are set as eccentric arc-shaped outer walls, that is, when the contact point of the reed contacts the outer periphery of the wheel convexity, the washing cam 510 rotates, and the contact point has a tendency to climb on the outer periphery of the wheel convexity, and the contact point position gradually moves away from the cam center in the radial direction of the soaking cam;
[0057] Reference Figure 3 As shown, the tail ends of the two wheel cams are both provided with a cut surface. When the contact moves to the tail end of the wheel cam, the cam continues to rotate, and the contact falls to the starting end of the next wheel cam.
[0058] The first washing reed 530 slides on the outer ring of the first wheel protrusion 511, and the second washing reed 540 slides on the outer ring of the second wheel protrusion 512;
[0059] First, when the first washing reed 530 is located on the first wheel convex 511, as the washing cam 510 rotates, the second washing reed 540 climbs on the second wheel convex 512, and when it climbs to the tail, it falls to the next second wheel convex 512 gap. At this time, the second washing reed 540 and the first washing reed 530 are in contact, and the washing mode is turned on. Figure 4 As shown;
[0060] The washing wheel convex continues to rotate, and the first washing reed 530 crawls on the first wheel convex 511, and at the same time, the second washing reed 540 crawls on the second wheel convex 512. At this time, the outer periphery of the first wheel convex 511 and the outer periphery of the second wheel convex 512 are on the same arc surface, so the first washing reed 530 and the second washing reed 540 remain in the connected state; until the first washing reed 530 climbs to the tail end of the first wheel convex 511 and falls onto the next first wheel convex 511, at which time the first washing reed 530 and the second washing reed 540 are disconnected, and the washing mode stops. Figure 5 shown.
[0061] In this embodiment, the outer diameter of the first wheel convex 511 is smaller than the outer diameter of the second wheel convex 511, and the rear arc surface of the first wheel convex 511 and the front arc surface of the second wheel convex 512 have an overlapping area, that is, the arc surfaces at both ends are on the same arc periphery, specifically refer to Figure 3 shown.
[0062] In this embodiment, the second quick-break structure is a first groove 412 and a first convex portion 411 provided on the first soaking cam 410; and a second convex portion 421 and a second groove 422 provided on the second soaking cam 420 corresponding thereto;
[0063] The first groove 412 corresponds to the second protrusion 421, so that the first soaked reed 450 and the second soaked reed 460 are in a connected state;
[0064] The first protrusion 411 corresponds to the second groove 422, so that the first soaked reed 450 and the second soaked reed 460 are in a disconnected state.
[0065] The first soaking cam 410 and the second soaking cam 420 are coaxially arranged and rotate at the same speed at the same time, that is, when the first groove 412 and the second protrusion 421 are a group of control positions, the first protrusion 411 and the second groove 422 are a group of control positions.
[0066] The soaking wheel assembly 400 further includes a first lever 430 and a second lever 440. The first lever 430 is driven by the first soaking cam 410 to pull the first soaking reed 450 toward the second soaking reed 460.
[0067] The second lever 440 is driven by the second soaking cam 420 to push the second soaking reed 460 to one side of the first soaking reed 450 .
[0068] When the first lever 430 is located in the first groove 412, the second lever 440 contacts the second protrusion 421. At this time, the first soaking reed 450 and the second soaking reed 460 are in a connected state. Figure 6 As shown;
[0069] When the first lever 430 contacts the first protrusion 411, the second lever 440 is located in the second groove 422. At this time, the first soaking reed 450 and the second soaking reed 460 are in a disconnected state. Figure 7 shown.
[0070] In this embodiment, the first immersion reed 450 is located on the side away from the immersion wheel group 400, and the first lever 430 pulls the first immersion reed 450 to make it contact with the second immersion reed 460; its specific implementation is: a push rod 431 is extended on the end surface of the first lever 430 toward the side of the first immersion reed 450, and the push rod 431 is located on the inner side of the first immersion reed 450, which is used to push the first immersion reed 450 outward.
[0071] When the first end of the first lever 430 is inserted into the first groove 412, the first lever 430 as a whole moves toward the soaking wheel assembly 400, so the push rod 431 does not act on the first soaking reed 450, and the first soaking reed 450 is in a natural state position;
[0072] When the first end of the first lever 430 contacts the first protrusion 411 , the first lever 430 as a whole moves toward the side of the principle soaking wheel assembly 400 , and then the push rod 431 pushes the first soaking reed 450 out to separate it from the second soaking reed 460 .
[0073] In order to achieve quick on and quick off of the soaking wheel assembly 400, in this embodiment, the horizontal cross-section of the first groove 412 is a triangle.
[0074] Preferably, in this embodiment, the two groove walls of the first groove 412 are a downward slope wall 412.1 and an upward slope wall 412.2 in the rotation direction of the escape wheel mechanism 200, and the slope of the downward slope wall 412.1 is greater than the slope of the upward slope wall 412.2.
[0075] The two side walls of the second convex portion 421 are an upslope end surface 422.1 and a downslope end surface 422.2 in the rotation direction. The upslope end surface 422.1 is configured as an arc-shaped end surface, and the downslope end surface 422.2 is configured as an inclined surface.
[0076] Preferably, the slope of the upslope end surface 422.1 is smaller than the slope of the downslope end surface 422.2.
[0077] Specific reference Figure 8 As shown, when the first lever 430 moves on the first soaking cam 410, it enters the first groove 412 along the downslope wall 412.1. At the same time, the second lever 440 slides along the second soaking cam 420 and climbs to the top of the second protrusion 421 along the second upslope end surface 422.1. Since the downslope wall 412.1 has a large slope, the first lever 430 suddenly falls into the first groove 412. At the same time, the upslope end surface 422.1 has a large slope. Under the same rotation angle, the second lever 440 can quickly climb to the top of the second protrusion 421, thereby realizing the quick connection between the first soaking reed 450 and the second soaking reed 460.
[0078] When breaking quickly, the first lever 430 climbs along the uphill end surface 422.1 to the first convex portion 411, and the first soaked reed 450 is quickly reset during the climbing process; at the same time, the second lever 440 moves along the downhill end surface 422.2 to the second concave portion, and the second soaked reed 460 is quickly reset, thereby achieving rapid separation of the first soaked reed 450 and the second soaked reed 460.
[0079] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
