Description
Technical Field
The application relates to the field of refrigerator parts, in particular to a misoperation blocking device, an ice making mechanism and a refrigerator.
Background
The existing automatic ice maker mainly comprises an ice maker bracket, an ice making tray, an ice detecting rod and a driving unit. The automatic ice maker probes whether enough ice blocks exist in the ice making assembly support through the ice probing rod so as to trigger the driving unit to turn over and distort the ice tray when the ice blocks are insufficient, and the ice blocks fall off in the ice making assembly support. The ice maker needs to trigger the water adding device to add water into the ice tray after completing the ice making action each time so as to execute the next ice making action.
However, after the ice tray is extracted from the ice maker assembly, the current ice maker assembly cannot identify the current state of the ice tray. Therefore, when the ice detecting rod detects that the ice in the ice making assembly bracket is insufficient, the ice making machine still executes an ice-empty mode under the condition of lacking the ice making tray, and water is filled into the ice making assembly through the water adding device. At this time, since no ice-making tray carries the water injection, the water may be scattered in the freezing chamber of the refrigerator.
In order to solve the problem, the existing automatic ice making device can be additionally provided with a magnet on an ice making tray bracket, and the position of the magnet is sensed by a magnetic sensing device so as to judge whether an ice making tray exists in an ice making machine assembly. However, electromagnetic sensing devices such as hall sensors are expensive, and therefore, such a method is rarely adopted in practical applications.

Fig. 1 is an ice making mechanism according to the present application, comprising:
the ice making assembly bracket 1 is arranged in the refrigerator, is connected with a water inlet pipeline, is communicated with a cold air channel of the refrigerator and can provide a low-temperature environment required by ice making;
the ice-making tray 2 is detachably arranged in the ice-making assembly bracket 1, is provided with an ice-making groove in the ice-making tray, can receive water and can prepare the water stored in the ice-making tray into ice blocks required by a user under a low-temperature environment provided by the ice-making assembly bracket;
the ice detecting rod 3 is rotatably arranged on one side of the ice making assembly bracket 1 and can extend into the ice making assembly bracket 1 to detect the storage amount of ice blocks in the ice making assembly bracket 1 according to whether the ice blocks are contacted or not or according to the depth of the blocking position of the ice blocks, so that when the ice blocks are insufficient, the water inlet pipeline is triggered to discharge water into the ice making tray to make ice;
in order to avoid the misjudgment caused by the fact that the ice detecting rod cannot contact the ice making tray and ice blocks after the ice making tray is detached, a malfunction blocking device which can rotate along with the disassembly and assembly state of the ice making tray is arranged on one side, close to the ice detecting rod, of the side wall of the ice making assembly support 1 in a mode of a graph 2. The false action blocking device is rotatably arranged between the ice making assembly bracket 1 and the ice detecting rod 3 and is positioned on the dismounting path of the ice making tray 2. Therefore, when the ice-making tray 2 is installed in the ice-making assembly bracket 1, the false operation blocking device 5 is triggered by the ice-making tray and is arranged at the first position and is out of the stroke range of the ice detecting rod, and at the moment, the ice detecting rod 3 can normally extend into the ice-making assembly bracket 1 to contact ice blocks so as to trigger whether the water inlet pipeline is triggered to discharge water according to the ice block storage amount switching; when the ice-making tray 2 is taken out from the ice-making assembly bracket 1, the false operation blocking device 5 can automatically rotate to the second position and block in the stroke range of the ice detecting rod, and at the moment, the ice detecting rod 3 rotates inwards to directly abut against the outer side of the false operation blocking device 5 when performing ice detecting action, is limited by the false operation blocking device and is kept in a full ice state, and the water inlet pipeline cannot be triggered to discharge water.
From this, this application can be through blockking that the probe ice pole simulates full ice state, and the device of adding water in the restriction inlet channel can not take out the state at the ice making dish and annotate water in to the ice machine assembly to the protection ice making assembly support can not be judged by mistake and trigger the water injection, makes water unrestrained in the refrigerator freezer compartment.
Referring to fig. 3, in order to realize the above function, the present application may specifically provide the above malfunction blocking apparatus 5 to include:
a rotation shaft 50 rotatably installed in the open interior of the side wall of the ice making assembly support 1;
a stop lever 53 fixedly connected to the outer side of the rotating shaft 50 and extending below the rotating shaft 50 to be separated from the moving path of the ice detecting lever and abutted against the probe ice block when the ice making tray is pushed to rotate to the first position at the side of the ice making assembly bracket, and to be automatically driven by the self gravity to rotate to the second position at the lower part of the ice making assembly bracket after the ice making tray is withdrawn, so as to block the ice detecting lever from further extending into the ice making box on the moving path of the probe ice block abutted against the probe ice block;
the triggering part 52 is fixedly connected to the inner side of the rotating shaft 50 and located above the rotating shaft 50, and in order to ensure that the triggering part is limited and triggered by the ice tray and always kept at the first position in the installation state of the ice making box so as to prevent the false operation of the stop lever from abutting against the ice detecting lever to influence the normal ice making process, the triggering part is further extended into the ice making tray guide rail 11 for mounting and dismounting the ice tray in the ice making assembly bracket in a manner shown in fig. 4;
therefore, when the ice making tray enters the ice making assembly bracket from front to back along the ice making tray guide rail 11 for installation, and when the ice making tray slides to the rear side of the inside of the ice making assembly bracket along the ice making tray guide rail 11 and passes through the false action blocking device 5, the trigger part 52 positioned at the top of the false action blocking device 5 is pushed backwards by the guide piece matched with the ice making tray guide rail on the outer side of the ice making tray and is pressed to turn to the first position on the lower side of the ice making tray. At this time, the lever 53 is correspondingly pushed to turn forward to the upper side of the ice making assembly stand. The rotation center of the ice detecting rod 3 is arranged at the rear side of the ice making assembly bracket, the ice detecting rod needs to rotate forwards and inwards when detecting the ice storage amount, and the misoperation blocking device arranged at the front side of the ice detecting rod rotates towards the front side of the entrance of the ice making disc to the outside of the stroke range of the inward rotation of the ice detecting rod, so that the misoperation blocking device cannot influence the ice detecting rod entering the ice making assembly bracket to detect the ice storage amount. Therefore, the invention can always limit the trigger part 52 below the bottom surface of the ice making tray 2 by the guide piece of the ice making tray side part through pushing, pressing and abutting the ice making tray side part in the installation state of the ice making tray, thereby always keeping the outer gear lever always at the first position at the front side of the ice detecting lever stroke range and not being touched by the ice detecting lever to influence the ice detecting and storing amount;
and in the process that the ice making tray slides out of the ice making assembly bracket from back to front along the ice making tray guide rail 11 for detachment, when the ice making tray slides to the front side of the outside of the ice making assembly bracket along the ice making tray guide rail 11 and moves out of the position of the malfunction blocking device 5, the baffle plate positioned at the bottom of the malfunction blocking device 5 is automatically driven to rotate downwards under the action of the gravity of the baffle plate, and the triggering part 52 at the top of the malfunction blocking device is separated from the limit of the ice making tray outside guide piece and the ice making tray guide rail and is pushed to rotate upwards to the upper part of the inside of the ice making tray guide rail 11 by the rotation of the baffle plate. At this time, the shutter is automatically rotated to a first position on the lower side of the ice making tray. When the ice detecting rod 3 takes the rear side rotation center as a rotation axis to detect the ice storage amount in the ice making assembly bracket inwards, the ice detecting rod rotates forwards and inwards, and the misoperation blocking device positioned on the front side of the ice detecting rod rotates downwards to reach the stroke range of the inward rotation of the ice detecting rod, so that the misoperation blocking device directly blocks the inner side of the ice detecting rod at the moment, prevents the ice detecting rod from further rotating to the inside of the ice making assembly bracket, and avoids the ice detecting rod from detecting the ice storage amount under the error state of the ice making box under the disassembly condition. Therefore, the invention can always keep the trigger part 52 above the ice making tray guide track 11 arranged outside the ice making tray by the self weight of the blocking lever only when the ice making tray is detached, thereby always keeping the blocking lever outside in the second position inside the travel range of the ice detecting lever, blocking the blocking lever in the travel range inside the ice detecting lever and avoiding the continuous detection of the ice storage amount. In this state, the trigger 52 protrudes from the detaching path of the ice tray 2, so that when the ice tray is loaded, the trigger can still be accurately contacted with the trigger, and the trigger is pressed and pushed back to the bottom of the ice tray, so as to correspondingly adjust the malfunction blocking device to the first position, thereby clearing the obstruction of the ice detecting rod in detecting the ice storage amount.
In the concrete implementation, the ice making tray guide rail 11 arranged on the inner wall of the ice making assembly bracket 1 can be directly realized through the horizontal boss. The top of the outer side of the ice making tray is provided with a guide piece which can slide along the top end face of the boss, so that the dismounting path of the ice making tray is limited to a translation path along the upper surface of the ice making tray guide rail 11. In order to ensure the triggering of the trigger part of the false action blocking device, the ice making tray side wall and the inner side guide rail thereof are correspondingly disconnected at the position close to the top end of the ice detecting rod 3, so that a through hole and a gap for installing the false action blocking device are formed. Thus, the trigger 52 at the top of the malfunction prevention device 5 can pass through the through hole on the side wall of the ice making assembly holder at the side of the gap and enter the malfunction prevention device installation gap in the ice making tray guide rail 11. At this time, when the ice-making tray is loaded into the ice-making tray guide rail 11 and the malfunction blocking device 5 is pushed to the first position, the trigger part 52 turns into the malfunction blocking device mounting gap, is positioned at the lower side of the ice-making tray guide rail, and is always limited by the bottom surface of the guide sheet at the top of the ice-making tray; when the ice-making tray is detached from the ice-making tray guide rail and the malfunction blocking device 5 freely turns to the second position, the trigger part 52 can automatically rotate out of the malfunction blocking device installation gap and protrude out of the upper surface of the ice-making tray guide rail, so as to provide trigger when the ice-making tray is installed again.
Referring to fig. 3, the stop bar 53 may be further formed at its bottom end with a ledge extending outward and close to the ice-detecting bar when the stop bar is specifically disposed. Therefore, when the ice detecting rod 3 rotates inwards to abut against the stop lever in the state that the ice making tray 2 is disassembled, the inner side of the ice detecting rod can further abut inwards to a triangular area between the upper part of the crosspiece and the outer side wall of the stop lever 53, and the stop lever which is vertically arranged and the crosspiece which is horizontally arranged are used for limiting together, so that the ice detecting rod is prevented from being separated from the misoperation blocking device; when the ice making tray 2 is installed, the crosspiece and the stopper rod are turned forwards and upwards to the outside of the range which can be reached by the tail end of the ice detecting rod 3, and the crosspiece is separated from the contact with the ice detecting rod 3, so that the influence on the normal ice detecting and storing amount of the ice detecting rod is avoided.
In order to further ensure that the malfunction prevention device can rapidly fall to the second position after the ice tray is detached, in some implementations, a gravity driving terminal 55 is further disposed between the blocking lever 53 and the triggering portion 52 to further provide a steering torque by the weight of the gravity driving terminal, so that the malfunction prevention device can smoothly and rapidly rotate downwards to the second position. The gravity driving terminal may be disposed at a front side of the triggering portion 52 in a direction in which the ice making tray 2 is mounted, between the stopper rod and a mounting entrance at which the ice making tray is mounted. In the state where the ice tray 2 is removed, the gravity driving terminal provides a torque to offset the weight of the trigger 52 from the front side of the rotation shaft 50, thereby reducing resistance required to be resisted when the lever rotates downward, and thus providing a torque to drive the lever 53 to turn downward by its own gravity. After the ice-making tray 2 is installed and enters the ice-making tray guide rail, the gravity driving terminal can rotate backwards along with the trigger part and upwards turn over along the installation direction of the ice-making tray 2 to be close to the upper surface of the ice-making tray guide rail, and the gravity driving terminal and the trigger part provide limit for the stop lever, so that the stop lever does not influence the ice detecting lever to detect the ice storage amount after the ice-making tray is correctly installed.
Referring to fig. 5, in a preferred implementation manner, in order to further ensure that the malfunction prevention device can stably rotate on the side wall of the ice making assembly bracket without being mistakenly bumped and dropped due to repeated assembly and disassembly of the ice making tray, the present application may further preferably set the opening position where the malfunction prevention device is installed as a fan-shaped installation groove 4 opened on the side wall of the ice making assembly bracket 1, the bottom of the fan-shaped installation groove may be provided with a rotating shaft limiting groove 40 connected to the inside of the mounting gap of the malfunction prevention device, and the rotating shaft 50 may be rotatably installed in the rotating shaft limiting groove 40. The opening at the top of the shaft-limiting groove 40 may be slightly smaller than the diameter of the shaft to prevent the shaft from falling off. The inner side of the rotating shaft is provided with a disk-shaped rotating shaft limiting terminal 54 with the diameter slightly larger than the outer diameter of the rotating shaft limiting groove, and the rotating shaft limiting terminal 54 is clamped at the inner side end part of the rotating shaft limiting groove to provide limiting, so that the rotating shaft is further prevented from separating from the installation gap. In order to avoid the back of the stop lever at the outer side of the rotating shaft from rubbing the end surface at the outer side of the limiting groove of the rotating shaft and influencing the rotation of the misoperation blocking device, the outer end surface of the limiting groove 40 of the rotating shaft can be further set into a convex arc surface so as to reduce the friction between the contact surfaces of the two parts.
Considering that the lever and the trigger are located outside and inside the rotating shaft, respectively, the present application further generally provides a horizontally disposed circular arc connecting surface 51 above the rotating shaft 50. The outer end of the arc connecting surface 51 is connected to the top of the stopper 53, and the inner end is connected to the triggering portion 52 and the bottom of the gravity driving terminal 55. The circular arc connecting surface 51 rotates in the sector installation groove 4 above the rotating shaft limiting groove 40 by taking the rotating shaft as a center in the rotating process of the stop lever and the trigger part. In order to avoid the rotation range of the arc connection surface 51 limited by the blocking of the fan-shaped mounting groove 4 in the rotation process, the bottom of the fan-shaped mounting groove 4 is further provided with a turnover notch 41 at the outer side of the rotating shaft limiting groove 40 by the back position in the mode shown at the lower right corner of fig. 5. Therefore, after the ice tray is installed, the triggering part 52 and the gravity driving terminal 55 are turned backwards, and the arc connecting surface 51 may further enter the inside of the turning notch 41 downwards after reaching the rear end of the fan-shaped installation groove 4 to increase the height of the front end of the stopper rod. From this, under the ice-making dish 2 dismantlement state, pin 53 upwards overturns, and the circular arc of its top is connected face 51 and is rotated downwards to upset breach 41 in, can provide bigger activity space for exploring ice rod, further reduces this application pin under the normal operating condition to exploring ice rod's influence.
In order to keep the malfunction blocking device integrally stable in the rotating process of the stop lever, a circle of thin wall surface can be further arranged on the periphery of the fan-shaped mounting groove 4 in a mode shown in figure 6, so that the stop lever is abutted to the inner side of the stop lever through the thin wall surface to limit the deflection of the stop lever in the inner and outer directions of the side wall of the ice making assembly bracket, and the stop lever is ensured to basically rotate along the plane parallel to the side wall of the ice making assembly bracket. The triggering part 52 and the gravity driving terminal 55 are both arranged on the inner side of the thin wall surface and rotate in the installation gap formed in the ice making tray guide track, and the stop lever 53 is limited on the outer side of the outer wall of the ice making assembly bracket by the rotating shaft and the thin wall surface together, so that the limiting abutting of the ice detecting lever is provided or the triggering part can be kept to be stably contacted with the ice making box.
Fig. 7 shows that the ice making tray 2 of the present application pushes the triggering portion 52 to turn downward along the installation direction of the ice making tray 2 during installation along the ice making tray guide track, so as to drive the stop lever 53 to rotate upward to the first position, and withdraw from the range of travel of the ice detecting lever 3; then the ice making tray 2 is separated from the triggering part 52 in the process of detaching along the ice making tray guide rail, and the blocking lever 53 freely rotates downwards to the second position to block the whole process in the stroke range of the ice detecting lever 3.
This application realizes the hindrance and the butt of exploring ice pole after ice making dish dismantles through the shelves lever structure cooperation crosspiece of individual one deck. After the ice making tray is installed back to the ice making assembly bracket along the ice making tray guide rail, the stopper rod can be rapidly pushed to be separated from abutting connection with the ice detecting rod through the installation gap, the ice making tray guide rail and the trigger part arranged between the ice making tray guide rail and the ice making tray guide rail, and limitation to the ice detecting rod in a normal working state and an ice making state is cancelled. The scheme that this application provided can stop the probe rod when the ice making dish is dismantled in the loading and unloading state of automatic response ice making dish, and the simulation is full of ice state, sets for and adds water installation and no longer to ice machine assembly internal water injection, avoids probe rod misjudgement to trigger water injection, makes water unrestrained in the refrigerator freezer room to do not influence probe rod normal execution under the normal operating condition of ice making dish simultaneously and survey the ice storage volume.
