The specific embodiment
In the middle of explanation, and there being the identical parts of technology to use identical symbol, and no longer carefully state.To shown in Figure 9, refrigerator provided by the invention comprises with deicing as Fig. 3: but be arranged on the inside of refrigerating chamber 21 and the ice container 61 of stored ice 62a; Can send sending of ice container 61 inner ice cube 62a in rotary manner and ice screw rod 63; Be arranged on the side of ice container 61, can will send the ice ice cube 62a that screw rod 63 is sent to be broken into the 1st deicing 65 of the ice cube 62b with a certain size; With the downside that is arranged on the 1st deicing 65, the ice cube 62b of the 1st deicing 65 processing can be broken into the 2nd deicing 85 of small ice cube 62c.The upper inside of refrigerating chamber 21 is provided with the automatic ice maker 25 that can make ice cube 62a, and is provided with the ice container 61 that can collect and store the ice cube 62a that falls from automatic ice maker 25 at the lower end edge fore-and-aft direction of automatic ice maker 25.The inside of ice container 61 be provided with can send the screw type that is stored in its inner ice cube 62a send ice screw rod 63, and rear side being provided with of ice container 61 can rotate send ice screw rod 63 screw drive motor 64.Send the front end of ice screw rod 63 to be provided with the guider 67 of being furnished with the screw type blade, and on the axle center of guider 67, be provided with and ice the 1st rotating shaft 66 that screw rod 63 rotates with sending.Described the 1st deicing 65 comprises: the open trash ice chamber 68 the 1st in side and bottom that is arranged on ice container 61; Be fixed on the 1st fixed cutter 69 of 68 inside, trash ice chamber the 1st; Form one and rotating the 1st rotary cutter 70 with the 1st rotating shaft 66 that extends to 68 inside, trash ice chamber the 1st; With the radius of turn outside that is arranged on the 1st rotary cutter 70, the 1st blocking-up plate 71 that can between the release position that the ice cube 62a that will move to 68 inside, trash ice chamber the 1st causes the trash ice position on the 1st fixed cutter 69 and ice cube 62a is fallen, change.Radial direction along the 1st rotating shaft 66 is provided with some to separated by a distance at the length direction of rotating shaft 66, and the 1st rotary cutter 70 that on direction of rotation, has 180 degree phase differences, and be combined on the 1st rotating shaft 66 being provided with an end between the 1st rotary cutter 70 respectively, can carry out the 1st fixed cutter 69 of relative motion thus with the 1st rotating shaft 66.The side of the 1st blocking-up plate 71 is provided with the control lever 73 that the 1st blocking-up plate 71 is changed between trash ice position and release position, the other end of control lever 73 is arranged on a side of screw drive motor 64, so that it can carry out relative motion with the 1st magnetic valve 75 of rotation control rod 73.The 2nd deicing 85 comprises: is positioned at the below of trash ice chamber 68 the 1st, can makes the ice cube 62b of the 1st deicing 65 processing drop to its inside, and the open respectively trash ice chamber 88 the 2nd in top and bottom; Can be the 2nd rotary cutter 90 that rotate at the center with inside that is arranged on trash ice chamber 88 the 2nd and the 2nd rotating shaft 86 that parallels with the 1st rotating shaft 66; Axis direction along the 2nd rotating shaft 86 is arranged between the 2nd rotary cutter 90, can make the 2nd fixed cutter 89 of relative the 2nd rotating shaft of one end 86 rotations thus; With the radius of turn outside that is arranged on the 2nd rotary cutter 90, can the ice cube 62b that the 1st deicing 65 is fallen cause the trash ice position on the 2nd fixed cutter 89 and the ice cube 62b that falls from the 1st deicing 65 is fallen into change between release position groove 26 in the 2nd block plate 91.Be provided with somely to the 2nd rotary cutter 90 along the axis direction of the 2nd rotating shaft 86 is separated by a distance, an end of this rotary cutter can rotate along the radial direction of the 2nd rotating shaft 86, and has 180 degree phase differences on the direction of rotation.The size of the ice cube 62c that pulverizes according to final needs, the 2nd fixed cutter 89 is separately fixed between the 2nd rotary cutter 90 along the axis direction of the 2nd rotating shaft 86, and is provided with the cutter drive motors 92 that can rotate the 2nd rotary cutter 90 in the side of trash ice chamber 88 the 2nd.To be the center with the rotating shaft rotating shaft that be arranged in parallel with the 1st blocking-up plate 71 rotate towards the direction opposite with the 1st blocking-up plate 71 the 2nd blocking-up plate 91, and be provided with the control lever 93 that can rotate the 2nd blocking-up plate 91 on the side of the 2nd blocking-up plate 91.The side of control lever 93 be provided with can rotation control rod 93 so that it can carry out the magnetic valve 95 of relative motion.Based on said structure, when needs are drawn ice cube 62a, as shown in Figure 7, utilize not shown controller to control the 1st magnetic valve 75, so that the 1st blocking-up plate 71 turns to the release position, control screw drive motor 64 simultaneously so that send the ice screw rod 63 rotations.When sending ice screw rod 63 to begin to rotate, the ice cube 62a that is stored in ice container 61 inside will shift to trash ice chamber 68 the 1st under the effect of sending ice screw rod 63, and will flow into the inside of trash ice chamber 68 the 1st under the effect of guider 67.When the ice cube 62a that flows into falls behind down, be drawn out on the distributor 27 by groove 26.When needs are drawn ice cube 62b, as shown in Figure 8, utilize controller to control the 1st magnetic valve 75, so that the 1st blocking-up plate 71 is in the trash ice position, control the 2nd magnetic valve 95 simultaneously, so that the 2nd blocking-up plate 91 is in the release position.When sending ice screw rod 63 to begin to rotate, the ice cube 62a of ice container 61 inside will flow into the inside of trash ice chamber 68 the 1st, and the ice cube 62a that is flowed into will be caused on the 1st fixed cutter 69 by the 1st blocking-up plate 71.At this moment, the 1st rotary cutter 70 can become the 1st fixed cutter 69 a certain size ice cube 62b with the ice cube 62a size degradation on the 1st blocking-up plate 71 in the process of rotation, and the ice cube 62b after the processing will fall in the groove 26 by trash ice chamber 88 the 2nd, is drawn out at last on the distributor 27.And when needs are drawn picture ice bits small ice cube 62c of a size, as shown in Figure 9, can utilize controller that the 1st blocking-up plate 71 and the 2nd blocking-up plate 91 are in respectively on the trash ice position, and drive screw drives motor 64 simultaneously, so that send ice screw rod 63 to begin rotation.The ice cube 62a that sends is broken into ice cube 62b earlier in the 1st deicing 65, fall then in the trash ice chamber 88 the 2nd, and the small ice 62b that falls is caused on the 2nd fixed cutter 89 by the 2nd blocking-up plate 91.At this moment, utilize controller to control cutter drive motors 92, so that the 2nd rotary cutter 90 rotates, and the 2nd fixed cutter 89 will be become small ice cube 62c by size degradation with the 2nd ice cube 62b that blocks on the plate 91 under the rotation of the 2nd rotary cutter 90, be drawn out to the refrigerator outside by groove 26 at last.
