It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

In the description of the present invention, it is to be understood that the terms "center", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", The orientation or positional relationship of the "top", "bottom", "inside", "outside" and the like is based on the orientation or positional relationship shown in the drawings, and is merely for convenience of description of the present invention and a simplified description, rather than indicating or implying The device or component referred to must have a particular orientation, is constructed and operated in a particular orientation, and thus is not to be construed as limiting the invention.

Referring to Fig. 2, the ice making device comprises a bracket 1, an ice making box 2 is arranged in the bracket 1, and the ice making box 2 is rotatable between an ice making position and a deicing position; the axial sides of the ice making box 2 are fixedly connected There is an anti-overflow disc 3, and a first overflow barrier 4 and a second overflow barrier 5 are provided on both sides of the radial direction. When the ice making box 2 is in the ice making position, the first overflow prevention baffle 4 and the second overflow prevention baffle 5 respectively abut against the side wall of the corresponding side of the ice making box 2; when the ice making box 2 is from the ice making position When turning to the de-icing position, the first spill prevention baffle 4 can be detached from the side wall on the side corresponding to the ice making box 2. When the ice making box 2 is in the ice making position, the first overflow prevention baffle 4 and the second overflow prevention baffle 5 abut against the ice making box 2 to prevent overflowing; and the ice making box 2 is turned from the ice making position In the de-icing position, the first overflow prevention baffle 4 and the second overflow prevention baffle 5 are kept detached from the ice making box 2, and the ice making box 2 performs a deicing operation.

The ice making device according to the embodiment of the present invention, with reference to FIGS. 2 to 3, includes a bracket 1 and a rotating shaft mounted therein, and the bracket 1 is hinged to the ice making box 2 through a rotating shaft. When the rotating shaft moves, the ice making box 2 follows It rotates between the ice making position and the deicing position. A first overflow barrier 4 is disposed in the bracket 1 at a radial side of the rotating shaft; wherein the first spill plate is hinged to the bracket 1. The limiting shaft is fixedly connected to the rotating shaft, and the limiting member is set as a cam structure. When the ice making box 2 is in the ice making position, the first overflow preventing baffle 4 and the outer wall of the corresponding side of the ice making box 2 and the limit respectively The outer wall of the smaller radius of the piece abuts; when the ice box 2 When the ice making position is turned to the de-icing position, the limiting member rotates simultaneously with the ice making box 2, and the first overflow prevention baffle 4 is pushed by the limiting member to make the first overflow preventing baffle 4 and the side wall of the limiting member The position is turned from the position where the radius of the limiting piece is small to the position with a larger radius, and since the distance from the edge of the ice making box 2 to the axis of the rotating shaft is smaller than the maximum diameter of the cam, the first overflow preventing baffle 4 and the ice making box are realized. 2 detached.

In the ice making device provided by the embodiment of the present invention, since the limiting member is a cam structure, when the ice making box 2 is in the ice making position, the first overflow preventing baffle 4 is respectively on the side corresponding to the radial direction of the ice making box 2 The side wall and the outer wall with the smaller radius of the limiting piece abut against each other to realize the function of sealing the water retaining; during the rotation of the ice making box 2 between the ice making position and the deicing position, the outer wall of the limiting piece has a larger radius An overflow prevention baffle 4 keeps the first overflow prevention baffle 4 away from the ice making box 2. Thus, during the process of turning the ice making box 2 to de-ice or returning to the ice making process, the first spill prevention baffle 4 is always in contact with the ice making box 2, and does not cause wear or water leakage of the ice making box 2. During the rotation of the limiting member, the first anti-overflow baffle 4 is always in contact with the outer wall of the limiting member, and the first anti-overflow baffle 4 and the limiting member operate relatively smoothly because the outer wall of the limiting member of the cam structure is smooth. The friction between the first anti-overflow baffle 4 and the limiting member is small, and no large noise is generated.

If the limiting member of the embodiment of the present invention is only used as a component for driving the first overflow prevention baffle 4 to rotate, it is necessary to additionally provide an overflow prevention baffle at both ends of the rotating shaft to prevent water on both sides of the ice making box 2 Overflow, this structure requires more parts and more complicated structures. Therefore, preferably, as shown in FIG. 2, the limiting member can be directly used as the spill prevention disc 3, and the overflow prevention disc 3 of the cam structure is fixedly connected to the axial ends of the rotating shaft of the ice making box 2, which can be realized. Driving the first overflow barrier 4 to rotate also prevents water from overflowing axially along the rotating shaft.

The anti-overflow disc 3 can be implemented in various manners. For example, a cam structure provided with a protrusion on the disc can be adopted. When the ice making box 2 is in the ice making position, the first overflow prevention baffle 4 and the anti-overflow disc 3 The outer wall of the disc abuts; when the ice making box 2 is turned to the de-icing position, the first overflow prevention baffle 4 moves to the outer wall of the overflow prevention tray 3, so that the first overflow prevention baffle 4 and the ice making box 2 Keep away from it, but the convex cam structure on the disc needs to occupy a large space inside the bracket 1. Therefore, preferably, referring to Figures 4 to 10, the spill prevention disc 3 comprises a circular disc body, the disc body edge is provided with a recess 31, and a convex cam knot is provided on the upper disc. Structure, which takes up less space. In addition, the axis of the rotating shaft passes through the center of the disk body, and the projection of the ice making box 2 on the plane of the disk body is located in the disk body, ensuring that the first overflow prevention baffle 4 is always in the process of rotating the ice making box 2 The ice box 2 is not in contact and does not cause wear of the ice box 2. Further, the first anti-overflow baffle 4 is correspondingly provided with a first rib 41 matched with the groove 31, and when the ice making box 2 is in the ice making position, the first ribs 41 respectively correspond to the ice making box 2 The side wall on one side and the recess 31 on the spill prevention disc 3 abut against each other, so that the first overflow barrier 4 is more closely fitted with the side wall of the ice maker 2 and the spill prevention disc 3. The first rib 41 is preferably located above the side wall of the corresponding side of the ice making box 2, and when water splashes onto the first spill guard 4, the water flow can flow along the side wall of the first spill guard 4 It is more convenient to flow into the ice making box 2 to the first rib 41.

When the ice making box 2 is in the ice making position, the first spill prevention baffle 4 abuts against the spill prevention disc 3 due to gravity. If the ice making device is shaken or the water flow hits the first overflow prevention baffle 4 or the like, the first overflow prevention baffle 4 may be pushed open to affect the anti-overflow effect. Therefore, preferably, the bracket 1 of the embodiment of the present invention further has an elastic member 43 mounted thereon, and the first overflow preventing baffle 4 is pressed against the two spill prevention discs 3 by the elastic member 43 to prevent the first operation of the ice making device. The overflow prevention baffle 4 is separated from the spill prevention disc 3 to ensure the stability of the overflow prevention effect.

The elastic member 43 may be a compression spring, a torsion spring or a tension spring. If the elastic 43 is a compression spring, the two ends of the elastic member 43 are respectively connected with the first overflow prevention baffle 4 and the bracket 1. During the operation of the ice making device, the elastic member 43 is always in a compressed state, and the first anti-overflow is given. The plate 4 applies a pushing force against the spill prevention disc 3, so that the first overflow prevention baffle 4 always abuts against the spill prevention disc 3, but a separate connection structure is required on the first overflow prevention baffle 4 and the inner wall of the bracket 1 The elastic member 43 can be connected to the elastic shaft 43. Therefore, if the elastic member 43 is a torsion spring, the elastic member 43 can be sleeved on the hinge shaft 42 of the bracket 1 and the first overflow prevention baffle 4, and the elastic member 43 One force receiving end abuts against the inner wall of the bracket 1 and the other force receiving end abuts against the first overflow preventing baffle 4. During the operation of the ice making device, the two stressed end ends of the elastic member 43 are always in a pressed state, and the elastic member 43 applies a reaction force to the first overflow preventing baffle 4, so that the first overflow preventing baffle 4 and the anti-overflow baffle 4 The overflow wall 3 and the outer wall of the corresponding side of the ice making box 2 abut each other, because the torsion spring and the bracket 1 and the first overflow prevention baffle 4 have a simple assembly structure, and the torsion spring is simple in manufacturing and processing, and the replacement cost is low. Therefore, the elastic member 43 in the embodiment of the present invention A torsion spring is preferably employed.

The embodiment of the present invention further includes a second overflow prevention baffle 5 located on the other side of the ice making box 2 in the radial direction of the rotation axis, opposite to the position of the first overflow prevention baffle 4, for preventing water from overflowing. The second overflow barrier 5 and the bracket 1 may be connected by a fixed connection or a detachable connection. If the upper end of the second overflow prevention baffle 5 is hinged to the bracket 1, the lower end presses the second overflow prevention baffle 5 against the outer wall of the corresponding side of the ice making box 2 by gravity, when the ice making box 2 is from the ice making position When rotating to the de-icing position, the ice making box 2 opens the second overflow prevention baffle 5 to realize the disengagement operation of the ice making box 2 and the second overflow prevention baffle 5, but when the ice making box 2 is subjected to impact or shaking The ice making box 2 is also easily disengaged from the second overflow prevention baffle 5, and affects the anti-overflow effect; if the second overflow prevention baffle 5 is fixed to the inner wall of the bracket 1, when the ice making box 2 is shaken, the second prevention The overflow baffle 5 is not hit by the ice box 2 by the ice box 2, and the second overflow prevention baffle 5 abuts against the outer wall of the corresponding side of the ice making box 2, and the spill prevention effect is good. Therefore, the second overflow guard baffle 5 and the bracket 1 are preferably fixedly connected between the embodiments of the present invention.

The second anti-overflow baffle 5 is preferably provided with a second rib 51 on the inner wall thereof. When the ice making box 2 is in the ice making position, the second overflow preventing baffle 5 corresponds to the ice making box 2 through the second rib 51. The outer wall of the side abuts, and the second rib 51 is located above the outer wall of the corresponding side of the ice box 2. Therefore, the second rib 51 not only facilitates the fall of the water into the ice making box 2, but also can return to the ice making position when the ice making box 2 reaches the ice making position when the ice making box 2 returns from the defrosting position to the ice making position. The ice box 2 cannot be stopped to rotate due to excessive impact, but turns to the de-icing position, but at this time, the side wall corresponding to the ice making box 2 through the second rib 51 has been pressed against the tightness, and the ice box is blocked. 2 reverse.

The ice making box 2 includes a plurality of ice making compartments for making ice. When the water splashes on the first overflow prevention baffle 4 and the second overflow prevention baffle 5, the water is blocked from the first overflow. The inner wall of the plate 4 and the second overflow prevention baffle 5 flows into the ice making box 2, but if the water flowing to the ice making box 2 does not flow into the ice making compartment in the ice making box 2, it stays in the ice making box 2 On the upper surface, if the ice making box 2 encounters shaking again, and the outer wall of the two sides of the ice making box 2 abuts against the first overflow prevention baffle 4 or the second overflow prevention baffle 5, the water is easy to be The outer wall of the ice making box 2 flows out. Therefore, preferably, the upper edge of the side wall of the ice making box 2 along the radial sides of the rotating shaft is higher than the upper surface of the ice making box 2, the first overflow prevention flap 4 and the second prevention The overflow baffle 5 respectively corresponds to The upper edge of one side wall abuts. When the water flows down from the inner walls of the first overflow prevention baffle 4 and the second overflow prevention baffle 5, even if it does not flow into the ice making compartment in the ice making box 2, it encounters shaking and stays on the upper surface of the ice making box 2. The water flows to the side walls on both sides of the ice making box 2, and the water does not overflow again due to being blocked. Further, in the process of preparing water for the ice making device to prepare ice, if the flow rate of the water is large, it can block the water flowing instantaneously into the side wall of the ice making box 2.

When the ice making box 2 is in the ice making position, the first overflow prevention baffle 4 and the second overflow prevention baffle 5 are both disposed obliquely toward the inner side above the ice making box 2, opposite to the first overflow prevention baffle 4 and the second prevention The overflow baffle 5 is installed upright, which not only increases the overflow prevention area of the ice making box 2, but also further increases the speed at which the water falls back to the ice making box 2 along the first overflow prevention baffle 4 and the second overflow prevention baffle 5. .

A refrigerator according to an embodiment of the present invention includes a cabinet, a door body 6, an outer cover panel 7, an ice making device 8, an ice storage tank 9 and an ice detecting rod 10, as shown in Figs. The refrigerator body is provided with a refrigerating chamber and a freezing chamber. The ice making device is installed on the door body, and the cold air is introduced into the ice making device through the outer cover plate to make ice, and at the same time, the ice making device is protected, and the ice making device is also under the ice making device. An ice storage bucket is installed for storing ice cubes detached from the ice making device, and an ice detecting rod is also mounted on the bracket of the ice making device for detecting the height of the ice cubes in the ice storage bucket, and when the ice detecting bar detects the ice When the block reaches a predetermined height, the ice making device stops the ice making operation.

The refrigerator of the embodiment of the present invention improves not only the anti-overflow disc 3 in the ice making device, the first overflow prevention baffle 4 and the elastic member 43, but also improves the sealing between the first overflow prevention baffle 4 and the ice making box 2. The anti-overflow effect is ensured, and the friction between the first overflow prevention baffle 4 and the axial side wall of the ice making box 2 is also reduced. The refrigerator of the embodiment of the invention has more powerful functions and high degree of automation, and has good anti-overflow effect and low noise during the operation of the refrigerator.

The water guiding funnel is a common flow guiding device. Referring to FIG. 15, the bucket body 11 and the upper and lower sides of the bucket body 11 are generally provided with an inlet 12 and an outlet 13. The inlet 12 of the bucket body 11 is provided with a funnel cover 14 which can be closed. And opening the inlet 12, the outlet 13 transfers water to other storage devices.

15 to 18, a water guiding funnel according to an embodiment of the present invention includes a bucket body 11 provided with an inlet 12 and an outlet 13, wherein the outlet 13 is located at the lowest point of the bottom plate of the bucket body 11, The bottom plate of the bucket body 11 is composed of at least three flow guiding surfaces, and the slopes of the adjacent two flow guiding surfaces are different.

In the water guiding funnel provided by the embodiment of the present invention, since the bottom plate of the bucket body 11 is composed of at least three flow guiding surfaces, and the inclination of the adjacent two guiding surfaces is different, the water flows along one of the guiding surfaces, in the flow process. In the middle, the water diverges and decelerates toward the other guiding surfaces around the water. Because the slopes of the adjacent two guiding surfaces are different, there is an angle between the adjacent two guiding surfaces, and the water is diffused on each guiding surface. The resistance increases and the water velocity decreases more quickly, so the diffusion distance required to reduce the water flow velocity to zero is relatively short; when the water velocity decreases to zero, the water accelerates to the outlet 13 under the action of gravity due to the diffusion of water. The distance is short, the acceleration distance when flowing to the outlet 13 is also short, and the acceleration time of gravity is not long, so the speed at which the water flows to the outlet 13 is low, and splashing is less likely to occur.

It should be noted that, in the embodiment of the present invention, the inclination of the flow guiding surface refers to the angle of the flow guiding surface with respect to the horizontal plane.

The bottom plate of the bucket body 11 is composed of a plurality of flow guiding surfaces, and the more the flow guiding surface, the more complicated the processing and the higher the cost. Therefore, preferably, the bottom plate of the bucket body 11 of the embodiment of the present invention is constituted by three flow guiding faces. If the slope of the flow guiding surface is too large, the speed of the water flowing to the outlet 13 is too high, and it is easy to cause splashing; if the inclination of the guiding surface is too small, the water flow rate is too slow, and the flow is caused by the surface tension of the water. There are a large number of water drops on the surface, and a large ice layer is easily formed on the flow guiding surface at a low temperature. Therefore, preferably, the first flow guiding surface 111 of the embodiment of the present invention has a slope ranging from 5° to 20°, and the second guiding surface 112 has a slope ranging from 5° to 30°, and the third guiding surface 113 The slope ranges from 5° to 30°, and the first flow guiding surface 111 is located between the second flow guiding surface 112 and the third flow guiding surface 113.

Specifically, the inclination of the first flow guiding surface 111 of the embodiment of the present invention is preferably 10°, the inclination of the second flow guiding surface 112 is preferably 20°, and the inclination of the third guiding surface 113 is preferably 20°. Therefore, the angle between the adjacent two flow guiding surfaces is not too large or too small, so that the bottom surface of the bucket body 11 can not only facilitate the diffusion of the water flow, but also effectively guide the water flow.

In an embodiment of the invention, the bucket body 11 further includes opposite first and second side walls, and opposite third and fourth side walls. The above four sides The wall encloses a flow path having a rectangular cross section, and the water flow flows downward by gravity in the rectangular flow path. Referring to FIGS. 19-23, the bottom plate of the bucket body 11 may adopt the following splicing manner: the first flow guiding surface 111 is an isosceles triangle, and the bottom edge thereof is spliced with the lower edge of the first side wall, and the second guiding surface 112 is And the third flow guiding surface 113 are both right-angled trapezoids, and the inclined waists of the second guiding surface 112 and the third guiding surface 113 are respectively spliced with the two waists of the first guiding surface 111, and the second guiding surface 112 and the The lower bottom of the third flow guiding surface 113 is respectively spliced with the lower edges of the third side wall and the fourth side wall, and the upper bottom surface of the second flow guiding surface 112 and the third flow guiding surface 113 are spliced to each other, the second guiding The right angle waists of the flow surface 112 and the third flow guiding surface 113 are spliced with the lower edge of the second side wall, and the outlet 13 is opened on the second flow guiding surface 112 or the third flow guiding surface 113, and is close to the second guiding surface. The right angle waist of the 112 or third flow guiding surface 113 is set. The above splicing structure is simple, and can effectively enhance the buffering effect of the bottom plate of the bucket body 11.

When water is added, if water is added to the first flow guiding surface 111, since the first flow guiding surface 111 is located between the second flow guiding surface 112 and the third flow guiding surface 113, the water is downward along the first guiding surface 111. When flowing, the second flow guiding surface 112 and the third flow guiding surface 113 on both sides can be simultaneously diffused, so that the second flow guiding surface 112 and the third flow guiding surface 113 can be effectively utilized, so that the diffusion distance of the water flow is short, and the buffering is performed. The effect is better; if water is added to the second flow guiding surface 112, the water flow is diffused from the second flow guiding surface 112 to the first guiding surface 111, and further diffused to the third guiding surface 113, because the third guiding surface 113 It is far away from the second flow guiding surface 112, and its buffering effect on the water flow is small. Similarly, if the third flow guiding surface 113 is used as the flow surface of the water, the second guiding surface 112 has little buffering effect on the water flow. . Therefore, preferably, the first flow guiding surface 111 is preferably aligned when water is added.

In order to prevent the water from staying on the outer surface of the bottom of the water retaining funnel under the surface tension to generate ice particles, a fence structure 15 is further provided on the outer wall of the bottom plate of the bucket body 11 near the outlet 13 so that the water flow can be directed to the fence structure 15 The lower surface does not flow to the bottom of the water retaining funnel.

In the embodiment of the present invention, the funnel cover 14 is mounted at the inlet 12 of the bucket body 11, and the funnel cover 14 is smaller than the inlet area of the bucket body 11, and at least a portion of the funnel cover 14 covers the outlet 13. The funnel cover 14 not only has a certain dustproof effect, but also does not need to flip the cover when manually adding water, and can directly add water to the funnel inlet 12; By closing the upper inlet 12 of the outlet 13, it is possible to prevent the water from being directly poured out from the outlet 13 when the water is manually added, and the buffer is not obtained.
