Description

Technical Field

[0001] The invention belongs to the technical field of household appliance execution devices, and in particular relates to a hinged frame automatic lifting in-and-out integrated dishwasher. Background Art

[0002] With the continuous development and progress of society, people's demand for the quality and refinement of home appliances has gradually increased. At present, especially high-end home appliances, in addition to having basic functions, are also required to be safe and reliable to use, convenient and friendly to operate, and give people a refined and elegant feeling. Take the dishwasher as an example. Because the lower bowl basket is located at a low position, the operator needs to bend down and stand up many times when taking and placing bowls. The operation is not convenient, especially for the elderly, and the operation is very unfriendly. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the present invention provides a hinged frame automatic lifting in-and-out integrated dishwashing cabinet, which can safely and reliably realize the manual and automatic in-and-out and lifting and lowering operations of the bowl basket with a simple structure and controllable cost.

[0004] In order to achieve the above-mentioned purpose, the present invention is realized through the following technical scheme: a hinged frame type automatic lifting and in-and-out integrated dishwashing cabinet, comprising a cabinet body, a first bowl basket, and a lifting and in-and-out actuator; the lifting and in-and-out actuator is arranged in the cabinet body; the first bowl basket is arranged on the lifting and in-and-out actuator, and is driven to lift and move in and out by the lifting and in-and-out actuator.

[0005] The lifting and in-and-out actuator includes a pair of arc-shaped guide rails, a hinge, a bracket, and a driving device; the pair of arc-shaped guide rails are fixedly arranged; one end of the hinge is fixedly hinged (the so-called fixed hinged arrangement refers to being hinged on a fixed object), which is recorded as the fixed end, and the other end is recorded as the movable end, and the movable end is hinged to the bracket; support rods are also arranged on both sides of the bracket, and the support rods slide along the arc-shaped guide rails; the driving device can drive the hinge to rotate.

[0006] The arc guide rail is fixed in the cabinet; the fixed end of the hinge frame is hinged in the cabinet; the driving device is connected between the cabinet and the hinge frame; and the first bowl basket is fixed on the bracket.

[0007] The bowl basket of the above-mentioned dishwashing cabinet has the function of automatically moving out and raising, and also has the function of automatically retracting and lowering. Specifically, when the bowl basket needs to be moved out and raised, the driving device is started to drive the hinge frame to rotate, so that the movable end of the hinge frame rises upward. As the movable end of the hinge frame rises, the bracket is also lifted upward along the arc guide rail. Since the arc guide rail is arranged obliquely upward as a whole, the bracket is lifted and moved outward along the arc guide rail. The bowl basket is automatically moved out and raised with the bracket. The automatic retraction and lowering operation of the bowl basket can be performed by simply reversing the driving device.

[0008] Furthermore, in the above-mentioned hinge-type automatic lifting in-and-out integrated dishwasher, the movable end of the hinge is also provided with at least one support buckle, and a bayonet is provided on the support buckle; when the hinge is swung upward, the support rod is snapped into the bayonet. The support buckle is provided to provide support for the support rod, and when the bracket is raised, the bracket can be kept stable and the shaking of the bracket can be reduced.

[0009] Furthermore, in the hinged frame type automatic lifting in-and-out integrated dishwasher, a cam bearing follower is provided on the support rod; the cam bearing follower is clamped into the arc guide rail and slides along the arc guide rail. The cam bearing follower has the function of guiding and reducing friction, and can withstand large loads, so that the bracket slides along the arc guide rail more smoothly.

[0010] Furthermore, the above-mentioned hinged automatic lifting in-and-out integrated dishwasher has a telescopic driving device, and any one of an electric cylinder, a pneumatic cylinder, a hydraulic cylinder, and a motor screw can be selected, or other existing telescopic driving devices with the same function can be selected.

[0011] Preferably, the driving device of the above-mentioned hinged frame automatic lifting in-and-out integrated dishwasher cabinet is an electric cylinder.

[0012] Furthermore, the above-mentioned hinged frame automatic lifting in and out integrated dishwasher is also provided with a limit pin on the top of the arc guide rail, and the limit pin runs through the arc guide rail. After the limit pin is set, the lifting in and out actuator also has the conditions for manual operation. Under normal working conditions, the lifting in and out actuator is driven by electricity, and the limit pin does not participate in the work. When the power is off, you can manually pull up the bowl basket and push the limit pin. The limit pin extends into the arc guide rail to hold up the support rod to prevent the bowl basket from sliding down. The above-mentioned dishwasher has both automatic and manual operation functions, and the selection of its electric cylinder should meet the following conditions: it is not locked in the power-off state, it is not locked when the power is output in the power-on state, and it is locked when the power output stops in the power-on state.

[0013] In addition, in order to further improve safety and reliability, the control logic of the above-mentioned electric cylinder can also be designed and expanded, including current overload protection design and execution time out-of-range protection design.

[0014] Furthermore, in the above-mentioned hinged frame type automatic lifting in-and-out integrated dishwashing cabinet, a second bowl basket is slidably provided in the cabinet body; the second bowl basket is located above the first bowl basket.

[0015] Beneficial effects: It can be seen from the above technical solutions that the hinged frame automatic lifting in and out integrated dishwashing cabinet provided by the present invention has a reasonable and ingenious design, a simple and compact structure, economical and controllable costs, and can safely and reliably realize the automatic in and out lifting operation and manual in and out lifting operation of the bowl basket.
