Detailed Description
Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present application and should not be construed as limiting the application.
A dishwasher and a door closing control apparatus thereof according to an embodiment of the present application will be described with reference to the accompanying drawings.
Fig. 1 is a block schematic view of a door closing control apparatus of a dishwasher according to an embodiment of the present application. As shown in fig. 1, a door closing control apparatus 1 of a dishwasher according to an embodiment of the present application includes: a gravity sensor 2, an action actuator 3 and a control module 4.
The gravity sensor 2 is used for detecting the weight of the inner container of the dish washer, the action executing mechanism 3 is used for executing the action of closing the door body of the dish washer when receiving a door closing driving signal, the control module 4 is respectively connected with the gravity sensor 2 and the action executing mechanism 3, and the control module 4 is used for generating the door closing driving signal when the weight of the inner container of the dish washer is kept unchanged and sending the door closing driving signal to the action executing mechanism.
That is, the gravity sensor 2 detects the weight of the inner container of the dishwasher in real time and transmits the weight of the inner container to the control module 4, the control module 4 receives the weight of the inner container and judges whether the weight of the inner container is continuously maintained, and generates a door closing driving signal when the weight of the inner container of the dishwasher is maintained, and transmits the door closing driving signal to the action actuating mechanism 3, and the action actuating mechanism 3 performs an action of closing the door body of the dishwasher when receiving the door closing driving signal.
It should be noted that, when the user takes out the tableware, the weight of the inner bag of dish washer constantly reduces until the user finishes taking, and at this moment, the weight of the inner bag of dish washer begins to remain unchanged, and when the user puts into the tableware, the weight of the inner bag of dish washer constantly increases until the placement finishes, and at this moment, the weight of the inner bag of dish washer begins to remain unchanged. That is, the door closing control of the dishwasher can be performed using the above-described apparatus regardless of whether the user takes out the dishes from the dishwasher or places the dishes in the dishwasher.
Therefore, when a user stops taking/placing tableware, the door closing control device can determine that the user finishes the operation of the tableware according to the fact that the weight of the liner is not changed, and further the door body of the dish washer is closed through the action executing mechanism, so that an automatic door closing effect is achieved, the user can use the door closing control device conveniently, the problem that the user cannot manually close the door after holding the tableware by two hands is solved, and the user experience is improved.
According to one embodiment of the application, the control module 4 starts timing when it receives the weight of the dishwasher's inner tub, and generates the door closing driving signal when the duration of the weight reaches a preset value.
That is, the control module 4 may be provided with a preset value of a duration in advance, the control module 4 starts timing when receiving the weight of the inner container of the dishwasher, then continuously determines whether the timing duration reaches the preset value, and generates a door closing driving signal and sends the door closing driving signal to the action executing mechanism 3 when the timing duration reaches the preset value, so that the action executing mechanism 3 executes an action of closing the door body of the dishwasher.
Further, after starting the timing, the control module 4 resumes the timing if the weight of the inner tub of the new dishwasher is received.
It should be understood that if the control module 4 receives the weight of the new liner of the dishwasher, it indicates that the user has performed an operation on the dishes, and therefore, it is necessary to restart the timing, so as to avoid the timing time according to the weight of the old liner reaching a preset value, and the door closing action caused thereby affecting the operation of the user.
Further, the specific mechanisms of the action actuator 3 in the embodiment of the present application may be various, and preferably, as shown in fig. 2 to 32, the action actuator 3 includes: as in the electric push rod 16 of fig. 13-15 and 24, the electric push rod 16 is capable of extending or retracting in response to a door closing drive signal; a door hinge mechanism as in fig. 9-15 and 20-21, which is capable of opening or closing a door of a dishwasher when the electric push rod 16 is extended or retracted.
Depending on the specific installation of the electric push rod 16, the electric push rod 16 may, for example, drive the door hinge mechanism to open the door body 7 of the dishwasher when extended and drive the door hinge to close the door body 7 of the dishwasher when retracted. Of course, the electric push rod 16 may be installed to close the door 7 when extended and to open the door 7 when contracted.
Further, as shown in fig. 2 to 6, the dish washer includes a cabinet 5 for accommodating dishes, and a door 7 mounted on a side of the cabinet 5.
The door body 7 hinge mechanism may include, for example: a base 8 as in fig. 22 and a web assembly 9 as in fig. 12-15.
In particular, as shown in fig. 4-8, the base 8 is fixed to the housing 5 of the dishwasher; as shown in fig. 12-13, the web assembly 9 connects the base 8 and the power pushrod 16, respectively, and is capable of sliding relative to the base 8 when the power pushrod 16 is extended or retracted.
More specifically, as shown in fig. 6 to 8, the base 8 may be mounted on, for example, an inner container of the cabinet 5 of the dish washer, as shown in fig. 22, the base 8 is formed to have limit grooves parallel to each other at both ends of the same side of a sliding panel and opposite to each other in opening, and as shown in fig. 13, the connection plate assembly 9 has a portion accommodated in the limit groove and is capable of sliding in the limit groove.
In one embodiment of the present application, the connection plate assembly 9 may include: the first slider 21 as in fig. 13-15 and 28, the second slider as in fig. 13-15 and 28, the ear plate 20 as in fig. 13-15, 20 and 27, and the connecting plate 21 as in fig. 13-15 and 29.
The first slider 21 is slidably mounted in a limit groove on one side of the base 8, the second slider 21 is slidably mounted in a limit groove on the other side of the base 8, one end of the ear plate 20 is hinged to the first slider 21, one end of the connecting plate 21 is hinged to the second slider 21, the other end of the connecting plate 21 is hinged to the other end of the ear plate 20, and the other end of the connecting plate 21 is connected to the electric push rod 16.
Thus, when the electric push rod 16 extends or contracts, the displacement of the first slide block 21 and the second slide block 21 in the limiting groove can realize the displacement of the connecting plate assembly 9 in the vertical direction, the hinging relationship between the lug plate 20 and the connecting plate 21 can realize the angular displacement of the connecting plate 21 in the vertical plane, and the door body 7 is turned and opened through the displacement of the connecting plate assembly 9 in the vertical direction and the angular displacement in the vertical plane.
In the specific installation, as shown in fig. 4 and 6, an elastic member may be further installed in the housing 5 of the dishwasher, for connecting the connection plate assembly 9, so as to facilitate the stable opening or closing of the door 7. The elastic member may be a tension spring.
In order to limit the opening angle of the door body 7, for example, limit the opening angle of the door body 7 to be within 90 ° as shown in fig. 29, a limiting piece 24 is provided on the connecting plate 21, as shown in fig. 22, a limiting post 17 is provided on the base 8, as shown in fig. 13, and the limiting piece 24 can abut against the limiting post 17 to limit the maximum opening angle of the door body 7 of the dishwasher. For example, when the door 7 is opened by 90 °, the connection plate 21 just moves to a position where the limiting piece 24 abuts against the limiting post 17, and the limiting action of the limiting post 17 makes the connection plate 21 unable to move continuously, so that the door 7 is restricted from rotating.
The electric push rod 16 may drive the door hinge mechanism to open or close the door body 7 of the pantile machine in various manners, for example, the electric push rod 16 may be directly connected to the connection plate 21, thereby driving the door body 7 to open or close. Or the electric push rod 16 is replaced by a pull rope, a motor is connected with the pull rope, the pull rope is connected with the connecting plate 21, the motor rotates to drive the pull rope to move, and then the pull rope pulls the connecting plate 21 to move so as to open or close the door body 7. Wherein the motor or electric push rod 16 of both embodiments generally needs to be mounted on the chassis of the dishwasher.
However, the inventor of the present application found in the study that when the door body 7 of the dishwasher is driven to be opened or closed by adopting the two structural forms, the space occupied by the door control system is large, and the size of the existing dishwasher is difficult to meet the installation of the door control system, so that the dishwasher with a larger structural size needs to be designed.
Based on this, the embodiment of the application provides a technical scheme capable of reducing the volume of the dish washer while realizing automatic opening or closing of the door body 7. Specifically, as shown in fig. 13 to 15, 21 and 29, the other end portion of the connecting plate 21 has a tooth mechanism 23, and as shown in fig. 13 to 15, the action actuator 3 further includes a tooth transmission mechanism through which the door hinge mechanism is connected to the electric push rod 16.
The tooth transmission mechanism is a mechanism for realizing transmission between components by engagement of the tooth structure 23, for example, transmission between gears and racks. The transmission effect of force and displacement between the electric push rod 16 and the connecting plate assembly 9 is realized through the tooth transmission mechanism, so that the whole mechanism of the door control system is more compact, the occupied space volume of the door control system can be reduced, and the volume of the dish washing machine is further reduced.
Specifically, the tooth transmission mechanism includes: the actuating rack 15 as in fig. 26, the drive rack 14 as in fig. 14-15 and 31 and the gear set 11 as in fig. 14-15 and 30.
Wherein, the rack 15 is connected with one end of the electric push rod 16, and the electric push rod 16 drives the execution rack 15 to move when extending or contracting; the drive rack 14 has a first rack section 28 with a larger tooth structure 23 and a second rack section 26 with a smaller tooth structure 23.
Wherein, as shown in fig. 14-15, the larger gear wheel 25 is engaged with the tooth structure 23 of the actuator rack 15 and the smaller gear wheel 26 is engaged with the second rack section 29 of the drive rack 14; the first rack section 28 of the drive rack 14 is glued to the tooth structure 23 of the other end of the connecting plate 21. When the electric push rod 16 pushes the execution rack 15 to move, the larger gear 25 drives the smaller gear 26 to rotate, the smaller gear 26 drives the driving rack 14 to move, and the driving rack 14 drives the connecting plate 21 to move, so that the transmission effect between the electric push rod 16 and the connecting plate assembly 9 is realized.
After the execution rack 15 and the electric push rod 16 are connected, the execution rack 15 and the electric push rod cannot move relative to each other. Thus, when the electric putter 16 is extended or contracted, the execution rack 15 moves in synchronization with the electric putter 16. Specifically, as shown in fig. 26, the execution rack 15 is formed with a mounting position, which may be, for example, a receiving groove capable of receiving the electric push rod 16, as shown in fig. 24, one end of the electric push rod 16 has a connection through hole, as shown in fig. 26, and the bottom of the receiving groove has a connection hole, as shown in fig. 14 to 15, and when the electric push rod 16 is connected, the connection can be implemented by a connection member penetrating the connection through hole and the connection hole, and the connection member may be, for example, a screw, a bolt, a pin shaft, or the like. As shown in fig. 15 and 26, the tooth pitch of the rack 15 and the size of each tooth are performed uniformly and equally, respectively.
In order to improve structural consistency and aesthetic appearance of the dishwasher, a hanger plate 6 is further installed outside the door body 7 of the dishwasher as shown in fig. 2 to 6, i.e., the door body 7 of the dishwasher includes an inner door assembly and the hanger plate 6 installed outside the inner door assembly as shown in fig. 2 to 6 and 9 to 11. When the dishwasher is in a closed state, as shown in fig. 2 and 4, the inner door assembly closes the inner container of the cabinet 5, and as shown in fig. 4, the bottom plate of the dishwasher is positioned lower than the inner door assembly. If the hanging plate 6 is not installed, the base of the dish washer is directly exposed to the outside, and the structural consistency and the appearance effect of the dish washer are affected. As shown in fig. 2 and 4, a hanging plate 6 is installed at the outer side of the inner door assembly, and the front side of the base of the dish washer is shielded by the hanging plate 6. Thus, structural consistency and good appearance effect of the dish washer can be ensured.
As shown in fig. 2 and 4, when the outside of the door body 7 of the dishwasher is the hanging plate 6, the distance between the hanging plate 6 and the tub of the dishwasher is relatively short. The hanging plate 6 easily blocks the rotation of the door body 7 during the opening process of the door body 7. In order to prevent the hanging plate 6 from obstructing the rotation of the door body 7, as shown in fig. 25, the action executing mechanism further comprises a hanging plate buckle 13 for connecting the hanging plate 6 on the door body 7 of the dish washer, as shown in fig. 26, the side part of the executing rack 15 is further provided with a hanging plate buckle positioning piece 19 for installing the hanging plate buckle 13, as shown in fig. 14-15, and the hanging plate 6 is driven to synchronously move by the hanging plate buckle 13 when the executing rack 15 moves. In particular, as shown in fig. 2 and 4, when the door 7 of the dishwasher is in a closed state, the top of the hanging plate 6 is substantially flush with the top of the dishwasher, and the bottom of the hanging plate 6 is close to the bottom of the dishwasher to shield the seat of the dishwasher. As shown in fig. 5 and 6, when the door body 7 of the dish washer is rotated to be opened, the hanging plate 6 is moved upward by the driving of the execution rack 15, and the bottom of the hanging plate 6 is moved upward, so that the obstruction to the rotation of the dish washer can be prevented.
As shown in fig. 25, the hanging plate buckle 13 can be connected with the hanging plate 6 through mounting holes formed on two sides of the lower part of the hanging plate buckle. The hanging plate buckle 13 has an accommodating groove for accommodating the hanging plate buckle positioning member 19 at an upper portion thereof, and as shown in fig. 26, the hanging plate buckle positioning member 19 may be a cylindrical positioning member, and thus, as shown in fig. 25, the accommodating groove may be a circular arc-shaped groove. In addition, in order to improve the compactness of the automatic door control system, as shown in fig. 25, a connecting upright post is further formed on the hanging plate buckle 13, and as shown in fig. 14-15, the hanging plate buckle 13 is mounted on the hanging plate buckle positioning piece 19, and meanwhile, the electric push rod 16 can be connected through the connecting upright post.
Further, as shown in fig. 12 to 13, 16 to 29, 21, 23 and 32, the motion actuator may further include a guide groove 12 and a connection seat 10, which may provide a guide space for movement of the actuator rack 15, the driving rack 14 and the electric push rod 16, and the guide groove 12 and the connection seat 10 are respectively fixed to the door body 7 of the dishwasher;
as shown in fig. 23, a guide hole 18 is formed in the side wall of the guide groove 12 along the length direction of the guide groove, as shown in fig. 12-13, an execution rack 15 and an electric push rod 16 are installed in the guide groove 12, as shown in fig. 12, a hanging plate buckle positioning piece 19 extends out of the guide groove 12 from the guide hole 18, and when the execution rack 15 moves, the hanging plate buckle positioning piece 19 also moves along the guide hole 18, so that the hanging plate buckle 13 is driven to move, and then the hanging plate 6 connected and fixed with the hanging plate buckle 13 is driven to move;
as shown in fig. 32, a through hole is formed in the side wall of the connection base 10, and as shown in fig. 12 and 13, the larger gear 25 is coaxially fixed with the smaller gear 26 by a shaft 27 passing through the through hole; as shown in fig. 13, the smaller gear 26 is located at the inner side of the connection base 10, as shown in fig. 12, the larger gear 25 is located at the outer side of the connection base 10, as shown in fig. 13, the driving rack 14 is installed in the connection base 10, and the connection plate 21 is hinged with the connection base 10.
