Description

Hinge bracket type automatic lifting and feeding integrated actuator

Technical Field

The invention belongs to the technical field of household appliance execution devices, and particularly relates to a hinged automatic lifting in-out integrated actuator.

Background

With the continuous development and progress of society, the quality and refinement requirements of people on household appliances are gradually improved. At present, especially high-end household appliances need to have basic use functions, and also need to be safe and reliable to use, convenient and friendly to operate and bring exquisite and elegant feeling to people. Taking a dish washer as an example, the lower layer bowl basket needs an operator to bend and get up many times when taking and placing bowls due to lower position, the operation convenience is not good, and especially for the old, the operation is not friendly.

Disclosure of Invention

In view of the above-mentioned deficiencies of the prior art, the invention provides a hinged-frame type automatic-lifting in-out integrated actuator, which can safely and reliably realize the manual-automatic integrated in-out and lifting execution operation with simple structure and controllable cost, and is particularly suitable for the automatic in-out and lifting operation of the lower-layer bowl basket of a dishwasher.

In order to achieve the purpose, the invention is realized by the following technical scheme: a hinge bracket type automatic lifting in-out integrated actuator comprises a pair of arc guide rails, a hinge bracket, a bracket and a driving device; the pair of arc guide rails is fixedly arranged; one end of the hinge frame is fixedly hinged (the fixed hinge is hinged on a fixed object), and is marked as a fixed end, the other end is marked as a movable end, and the movable end is hinged with the bracket; the two sides of the bracket are also provided with supporting rods which slide along the arc-shaped guide rails; the driving device can drive the hinge bracket to rotate.

The actuator can complete automatic lifting and feeding-in and feeding-out integrated execution operation, and can be widely applied to various household appliances. For ease of understanding, the operation of the actuator is described below by way of example in the context of use in a dishwashing cabinet, and not by way of any limitation to the actuator.

A hinge bracket type automatic lifting and feeding integrated dish washing cabinet comprises a cabinet body, a first dish basket and the hinge bracket type automatic lifting and feeding integrated actuator. The actuator is arranged in the cabinet body; the first bowl basket is arranged on the actuator and is driven by the actuator to lift and move in and out. Specifically, the arc-shaped guide rail is fixed in the cabinet body; the fixed end of the hinge bracket is hinged in the cabinet body; the driving device is connected between the cabinet body and the hinge bracket; the first bowl basket is fixed on the bracket.

The bowl basket of the dish washing cabinet has the functions of automatically moving out and lifting, and also has the functions of automatically retracting and descending. Specifically, when the bowl basket needs to be moved out and lifted, the driving device is started to drive the hinge frame to rotate, so that the movable end of the hinge frame is lifted upwards. As the movable end of the hinge bracket rises, the bracket also rises upwards along the arc-shaped guide rail. Because the arc-shaped guide rail is arranged obliquely upwards, the bracket is moved outwards while rising along the arc-shaped guide rail. The bowl basket is automatically moved out and lifted along with the bracket. The automatic withdrawing and descending operation of the bowl basket only needs to reversely operate the driving device.

Furthermore, the movable end of the hinge frame is also provided with at least one support buckle, and the support buckle is provided with a bayonet; when the hinge frame is swung upwards, the supporting rod is clamped into the bayonet. The supporting buckles are arranged to provide supporting effect for the supporting rods, the bracket can be kept stable after the bracket is lifted, and shaking of the bracket is reduced.

Furthermore, a cam bearing follower is arranged on the supporting rod; the cam bearing follower is snapped into and slides along the arcuate guide. The cam bearing follower has the functions of guiding and reducing friction, and can bear large load, so that the sliding of the bracket along the arc-shaped guide rail is more stable and smooth.

Furthermore, the driving device is a telescopic driving device, any one of an electric cylinder, an air cylinder, a hydraulic cylinder and a motor screw rod can be selected, and other existing telescopic driving devices with the same function can also be selected.

Preferably, the drive means is an electric cylinder. On the basis, the top of the arc-shaped guide rail is also provided with a limiting pin, and the limiting pin penetrates through the arc-shaped guide rail. After the limiting pin is arranged, the hinge frame type automatic lifting in-out integrated actuator also has the condition of manual operation. Under normal working conditions, the hinge bracket type automatic lifting in-out integrated actuator is driven by electric power, and the limiting pin does not participate in the work. When the power is off, the bowl basket can be manually pulled up and then the limiting pin is pushed, and the limiting pin extends into the arc-shaped guide rail to support the supporting rod, so that the bowl basket is prevented from sliding downwards. The dish washing cabinet has the functions of automatic operation and manual operation, and the electric cylinder selection of the dish washing cabinet meets the following conditions: the lock is not locked in the power-off state, the lock is not locked in the power output state in the power-on state, and the lock is locked in the power output stopping state in the power-on state.

In addition, in order to further improve the safety and the reliability, the control logic of the electric cylinder can be designed and expanded, and the control logic comprises a current overload protection design, an execution time out-of-range protection design and the like.

Has the advantages that: according to the technical scheme, the hinge frame type automatic lifting in-out integrated actuator provided by the invention has the advantages of reasonable and ingenious design, simple and compact structure, economic and controllable cost, and safe and reliable realization of automatic and manual in-out lifting integrated execution operation.
