With reference to fig. 10 to 11, in the present embodiment, the flexible sealing member has a primary surface 3132 facing to one side of the ice outlet, and the primary surface 3132 is parallel to a plane where the ice outlet is located. The concave varying portion 3131 is disposed on the base surface 3132, and is gradually concave from the base surface 3132 to a direction away from the ice outlet, and a side of the concave varying portion facing the ice outlet is an arc-shaped surface 31311. When the cover 3 is in the second position, under the driving of the driving mechanism 4, the flexible sealing element 313 of the cover 3 contacts and adheres to the matching surface 2 around the ice outlet, the concave variant portion 3131 deforms, at least a portion of air in the concave variant portion 3131 is exhausted, and the arc surface 31311 deforms to be substantially coplanar with the base surface 3132, so as to contact and adhere to the matching surface 2, thereby forming a vacuum or negative pressure between the matching surface 2 and the cover 3, so that the cover 3 tightly adheres to the matching surface 2, and the ice outlet is sealed.
The matching surface 2 is formed on the dispenser 1 or the ice outlet pipeline and surrounds the ice outlet. In the present embodiment, the matching surface 2 is formed on the dispenser 1 and surrounds the ice outlet, which is configured at the hole 11 as mentioned above, and the matching surface 2 correspondingly substantially surrounds the hole 11. In other embodiments, the matching surface 2 may also be formed on the ice outlet pipe and surround the ice outlet, for example, the matching surface 2 may be specifically configured as an end surface of the lower end of the ice outlet pipe.
Specifically, referring to fig. 4 and 5, the matching surface 2 is formed on a surface of the dispenser 1 facing away from the ice outlet, and the matching surface 2 is arranged in parallel with the primary surface 3132 of the flexible sealing member 313, so that when the cover 3 closes the ice outlet, the flexible sealing member 313 contacts and fits with the matching surface 2, and the arc surface 31311 of the concave varying portion 3131 deforms to contact and fit with the matching surface 2, so as to seal the ice outlet.
Further, in the embodiment, the matching surface 2 is an annular surface surrounding the ice outlet for a circle, so that the flexible sealing element 313 of the cover 3 and the arc-shaped surface 31311 of the concave varying portion 3131 are fittingly attached thereto, and the sealing effect is improved. The specific shape of the matching surface 2 can be a circular annular surface, a polygonal annular surface or an annular surface with other figures so as to surround the ice outlet for one circle, thereby being beneficial to enhancing the sealing effect.
To close the ice outlet while fitting the mating surface 2, referring to fig. 5 and 7, in the present embodiment, the cover 3 is circular, correspondingly, the flexible sealing member 313 is circular covering the cover 3, and the concave varied portion 3131 is annular fitting the mating surface 2. In other embodiments, the cover 3 may have a square, rectangular or oval shape as long as it can cover and close the ice outlet, and the flexible sealing member 313 and the concave variant 3131 are both adapted to the matching surface 2. When the depressed differential portion 3131 is in a natural state, the mating face 2 may completely cover the depressed differential portion 3131; when the cover 3 is in the second position, the arc-shaped surface 31311 of the concave varying portion 3131 deforms, and the matching surface 2 can still completely cover the concave varying portion 3131, so that a vacuum or negative pressure is formed between the concave varying portion 3131 and the matching surface 2 to increase the sealing of the ice outlet.

Further, referring to fig. 7 to 11, the cover 3 further includes a cover body 31 covering the ice outlet, the cover body 31 includes a rigid housing 311 and a heat insulating layer 312, wherein a flexible sealing member 313 is fixed on a side away from the rigid housing 311 to contact the fitting mating surface 2 to close the ice outlet; the heat insulation layer 312 is filled between the rigid shell 311 and the flexible sealing element 313, the heat insulation layer 312 is made of heat insulation foam or PE foam, and has a heat insulation effect, so that heat exchange between cold air in the ice outlet pipeline and air outside the ice maker is avoided; the rigid housing 311 can ensure that the cover 3 is pressed against the mating surface 2 by the driving mechanism 4, the flexible sealing member 313 contacts the mating surface 2 to close the ice outlet, and the end of the rigid housing 311 connected to the flexible sealing member 313 contacts the concave varying portion 3131, so that the rigid housing 311 acts on the concave varying portion 3131 by the driving mechanism 4 to exhaust the air in the concave varying portion 3131, and the concave varying portion 3131 is deformed to contact the mating surface 2.
When the cover 3 is in the second position, the flexible sealing member 313 contacts the fitting mating surface 2, and the concave varying portion 3131 deforms to contact the fitting mating surface 2. Specifically, when the cover 3 is in the second position, the driving mechanism 4 drives the cover 3 to make the flexible sealing member 313 contact and adhere to the mating surface 2 around the ice outlet, and further, the rigid housing 311 of the cover 3 transmits the driving force from the driving mechanism 4 to the concave varying portion 3131 to exhaust the air in the concave varying portion 3131, so that the concave varying portion 3131 deforms and forms a vacuum or negative pressure with the mating surface 2, thereby making the cover 3 adhere to the mating surface 2 tightly, and achieving the sealing of the ice outlet.
In the process of opening the cover 3, the cover 3 moves from the second position to the first position, and in order to overcome the vacuum or negative pressure between the concave varied portion 3131 and the mating surface 2, the opening may be opened from one side of the cover 3 first, so that the concave varied portion 3131 is separated from the mating surface 2 and returns to the deformation. When the deformation of the concave varied portion 3131 is completely recovered, a portion of the cover 3 leaves the matching surface 2 to form an opening, and a certain included angle is formed between the cover 3 and the matching surface 2, and at this time, the cover 3 is located at the third position.
Further, referring to fig. 6, 9 to 10, and 12, the drive mechanism 4 includes a first drive portion 41, and accordingly, the lid 3 includes a first portion 32 that is eccentrically disposed in the circumferential direction of the lid body 31. The first portion 32 is disposed eccentrically in the circumferential direction of the cover body 31, so that the driving mechanism 4 opens the notch from the side surface of the cover body 3 adjacent to the first portion 32 first, overcomes the vacuum or negative pressure between the concave varying portion 3131 and the mating surface 2, separates the concave varying portion 3131 from the mating surface 2 and recovers deformation, and the first driving portion 41 pulls the first portion 32 to move the cover body 3 to the third position, so that the cover body 3 is easily opened from one side of the cover body 3 against the vacuum or negative pressure first, and the resistance when the cover body 3 is opened is reduced.
When the cover 3 is at the second position, the first driving portion 41 drives the cover 3 to move from the second position to the third position by contacting the first portion 32, so that the concave varying portion 3131 is separated from the mating surface 2 and returns to the deformation.
Specifically, when the cover 3 is at the second position, the concave varying portion 3131 deforms to closely adhere to the mating surface 2, and at this time, the first driving portion 41 contacts the first portion 32 and provides a first driving force, and the first driving force pulls the first portion 32 to have a tendency of driving the cover 3 to leave the second position. The edge of the cover 3 adjacent to the first portion 32 of the cover 3, which is subjected to the first driving force, overcomes the vacuum or negative pressure between the concave varying portion 3131 and the mating surface 2, and separates from the mating surface 2, the concave varying portion 3131 recovers its shape in this area, and continues to apply a pulling force to the first portion 32 until the concave varying portion 3131 completely recovers its shape, the edge of the cover 3 adjacent to the first portion 32 separates from the mating surface 2, and the cover 3 moves to the third position. Through the cooperation of the first driving portion 41 and the first portion 32, the cover 3 is easily opened from one side of the cover 3 against vacuum or negative pressure, so that the resistance when the cover 3 is opened is reduced, the cover 3 is prevented from being difficult to open due to large stress when the cover 3 is opened from the middle of the cover 3, the damage to the driving mechanism 4 is reduced, and the service lives of the cover 3 and the driving mechanism 4 are prolonged.
Further, in the present embodiment, the driving mechanism 4 further includes a second driving portion 42, and accordingly, the cover 3 includes a second portion 33 connected to the body of the cover 3, that is, the second portion 33 is connected to the body of the cover 3. The second driving portion 42 cooperates with the second portion 33 to effect movement of the cover 3 by applying a force to the second portion 33. When the cover 3 is at the third position, the second driving portion 42 drives the cover 3 to move from the third position to the first position by contacting the second portion 33.
Specifically, referring to fig. 6, 8 to 9, the second portion 33 is disposed adjacent to the center of the cover body 31. When the cover 3 is at the third position, the concave varying portion 3131 returns to the shape, a certain angle is formed between the cover 3 and the mating surface 2, and the second driving portion 42 contacts the second portion 33 and provides a second driving force, which makes the second portion 33 have a tendency of pulling the cover 3 to move toward the first position. The lid 3 moves from the third position to the first position by receiving the second driving force. Through the cooperation of the second driving portion 42 and the second portion 33, the lid 3 is uniformly stressed in the process of opening the ice outlet, and the stability of the lid 3 is maintained.
Referring to fig. 6, in the present embodiment, the first portion 32 and the second portion 33 are respectively disposed in two horizontally arranged side by side, the first driving portion 41 is a rod-shaped member inserted into the two first portions 32, and the second driving portion 42 is a rod-shaped member inserted into the two second portions 33. Thus, the force bearing area of the cover body 3 can be increased, when the ice outlet is opened, the vacuum or negative pressure between the concave varied part 3131 and the matching surface 2 can be overcome more easily, and the resistance when the ice outlet is opened is reduced; when the ice outlet is closed, the cover 3 is uniformly stressed, so that the flexible sealing member 313 and the concave varied portion 3131 are more tightly attached to the mating surface 2, thereby ensuring the sealing effect.
Referring to fig. 8 to 10, in the present embodiment, the first portion 32 and the second portion 33 are both disposed on a side of the cover body 31 away from the ice outlet, that is, on the rigid housing 311 of the cover body 31. In this way, under the action of the driving mechanism 4, the cover body 3 applies a force to the cover body 31 to make it close to or far from the ice outlet by the cooperation of the first driving portion 41 and the first portion 32, and the cooperation of the second driving portion 42 and the second portion 33, so as to close or open the ice outlet.
Specifically, when the cover 3 is located at the second position, the concave varied portion 3131 deforms, and fits the mating surface 2 tightly, in order to open the ice outlet, the first driving portion 41 contacts and pulls the first portion 32, the cover 3 is driven by the first portion 32, the edge of the cover 3 adjacent to the first portion 32 overcomes the vacuum or negative pressure between the concave varied portion 3131 and the mating surface 2 first, the concave varied portion 3131 is separated from the mating surface 2 to form an opening, the concave varied portion 3131 recovers to deform, a certain included angle is formed between the cover 3 and the mating surface 2, and the cover 3 moves to the third position. That is, when the cover 3 is located at the second position, the first driving portion 41 may contact and pull the first portion 32 to drive the cover 3 to move to the third position.
When the cover 3 is located at the third position, the second driving portion 42 contacts and pulls the second portion 33, and at this time, the cover 3 simultaneously contacts with the first driving portion 41 and the second driving portion 42, and under the combined action of the first driving portion 41 and the second driving portion 42, the driving structure drives the cover 3 to move from the third position to the first position. That is, when the cover 3 is located at the third position, the first driving portion 41 contacts and pulls the first portion 32, and the second driving portion 42 contacts and pulls the second portion 33 to drive the cover 3 to move to the first position together.
